I'll let you make fun...

Nobody else I knew liked it.
Also liked Wall-e. Heartwarming movie right there.
You picked a drama and an animated movie? Cop out, brah. Both of those movies were reviewed ridiculously well, too. Although, A Time To Kill is pretty bad and will only ever be a To Kill A Mockingbird wannabe.
My answer:

For whatever reason, I could watch that movie a million times and never get tired of it. It's one of my guilty pleasures, up there with Limp Bizkit and Long John Silvers. Both of which give me fits of nausea and diarrhea.
Edited to add that I love Mean Girls and actually own it. Not even the least bit embarrassed about it.
