I personally think they are great. They are amusing and mischievous which makes the book fun to read. I like it when toi go to one of their scenes after a serious part. I never expected that one of the twins would die. That was a huge loss.
they are the life and humor and attractiveness (a real word? tbd) of the whole freaking HP series! my hogwarts charactr, Adora Shepperd, plans to elope with Fred but when he dies she marries Fred and gets ron jealous cuz they were bf and gf for a while. sorry if i got offtopic.
