These are my opinion reasons (Please do not bash on me for these opinions, they are my own thing and you are free to have your own opinion):

Favourite Character- I'm an aspiring actress and singer, Rachel is one of my role-models, despite the fact that she's fictional. The fact that she's so devoted and would NEVER give up her dreams excites me, she is so determined... even in popularity we match, we're both girls who simply want to be noticed.<3

Prettiest voice- Lea's voice is so stunning, it's incredible!<3

I miss her devotion- Rachel used to be a lot more determined, now she's letting things get in her way of her destiny... Finn and her marriage, to me, is distracting both of them from their futures, and it upsets me...

Liked her more in season 1- She was so ambitious and devoted... yet still the insecure, hopelessly in love girl that I connected to so well, I admired her<3

Song Connection- Most of her songs have something to do with heartbreak, which I've experienced a lot of... sad to say...

Her and Broadway- Finn and Rachel distract each other from their futures.

Relate to her- Look at the top :P

Hummelberry- My two favourite characters, along with the two characters I connect most to= PERFECTION<3 :D

Solos/screentime- It's not the Rachel show Ryan... it's called "Glee" it's about other people too.

Jar of Hearts- I don't really know why I like this one, I just do...<3 :P

Get It Right- I suffered through a breakup around the time of this song and kept wondering what I did wrong... this song really helped me connect to that... and the first time I listened to this song I thought of a rough patch my parents went through where they almost divorced, I was bawling my eyes out during the time and asked myself what I did to deserve such pain, and wished it just be right... this song really helped me connect with myself and heal<3

I liked her more in season 1 then I do now
I agree, I think Rachel was more likeble in season 1. She was headstrong, had her own dreams, and she was going to get there no matter what. But at the same time she wasn't always that cruel. I sometimes think she lost that part of her.

Out of all the female characters, I relate to Rachel most
DISAGREE, and this not because of her charector. In High school I wouldn't relate to Rachel at all. I was shy,I can't sing, and I would never step in front of an audience. I was more like Tina, in the back ground.

Rachel is one of my favourite characters
- In season 1, yes. Now I don't know who my favorite is. I guess I have to go for Tina, again I really was like her in High school. Minus the goth thing.

I think her voice is the prettiest of all the females
Kind off agree, I think Naya and Amber have killer voices, and I don't really know how to choose between them. And we can't forget about Jenna, who's overlooked a lot of the times. And Dianna can be amazing at times. But I like Shelby's vocals the best, but that's because I'm a big fan of Idina Menzel. So I couldn't really say who my favorite is between the castmembers.

I miss her devotion to Broadway/her devotion to be a star
I Agree, I was kind of disappointed in her when she didn't know that Cats wasn't playing on Broadway anymore. I was like, 'Rachel would know that'. I couldn't really believe Rachel wouldn't know that, I mean they should have given that line to someone else. Rachel always seemed to know each detail of Broadway. I think she should really try to proceed her dreams. They should give her the Broadway thing.

Rachel's songs connect to me emotionally more then any other character
About this I'm not sure, since I think all of them kind of do it. I wouldn't call Rachel the best, her singing is often very awkward instead off emotional. So, I don't really agree all the time.

I dislike her and Finn together as I ship her and broadway
I don't know, I actually think Rachel and Finn could make a good couple, but they are the kind of couple that meet on a ruenion and rekendle their relationship. Rachel should first think about her dream, and chase that. And it's very clear that her dream is Broadway.

Her and Kurt's friendship is my favourite on the whole show (tied with Furt)
I actually prefered his friendship with Mercedes in Season 1. Not that I don't like the friendship with Rachel, I guess I prefer Rachel, Mercedes and Kurt being friends.

I think she gets too many solos and too much screentime
I agree, some episodes there's to much Rachel. There are other charectors. That disserve time in the spotlight. Like Tina.

Jar of Hearts and Get it Right are my favourite Rachel solos
I agree, I like get it right. Don't really recall the jar of hearts song, so don't exactly remember if I like that song.

The Ones I Agree With
I think she gets too many solos and too much screentime. This, especially the fact that people like Tina and Brittany don't get that much. "She's the main character," the people say. There are other main characters, too, if you think about it.
I liked her more in season 1 than I do now. To me, that was the season where I can tolerate her. She had a couple of funny scenes and lines, and I enjoyed them. Now, she just...IDK. I don't like it anymore. It gets really annoying.
I dislike her and Finn together as I ship her and Broadway. She needs to follow her dreams and go to Broadway instead of sticking with the same guy for the rest of her life.

I pretty much disagree with the rest, though. I don't like Jar of Hearts as much as I like Take A Bow and Rolling in the Deep. Furt, Quinncedes, Furtory, and Quartie are my favorite friendships on the show. Santana and Mercedes, to me, have the prettiest female voices. I don't really relate to Rachel much, either. I mostly relate to Tina, Santana, Mercedes, and Quinn. Rachel is, for sure, not my favorite character.

The ones about connecting to songs emotionally and missing her devotion to Broadway, I somewhat agree with those, though.

I hate her Broadway obsession. I find her much more likeable when she's not focused on it.

I love that overtime her character grows and becomes more complex.
Finn and Rachel are perfect together!

I agree with a lot of these: I thing she gets to many solos, I don't like finchel(anymore) and want her to go with Broadway. I like some of her other solos better than those. I like Hummelberry, I like her better in season 1(mainly because she was just ambitious annoying. now she comes off much more selfish even if she isn't hogging as much of the solos).

What I disagree with most is relating to her. I can relate to everyone of the characters on some level. But the MOST. No. I relate to Tina, Brittany, and Santana the most(varying on the episode). I look the most like Rachel. but that's about it. Now the high school me would relate to her more but out of the females I relate to her the 2nd least then and now.

Hummelberry=cutest friendship ever to walk the earth.

Nothing beats Furt in my eyes lol!! :))

i agree with all of them, except this one

I agreed with all of them, except this one, she didn't gets to many solos and to much screentime? of couse she does!
I think the prettiest voices females are of: Quinn, Tina, Mercedes, Sunshine and Harmony then Santana, her and Marley

She just grew t much ! Still love her now :)

I disagree with most of them
