Considering the number of super hero movies, that could've been a genre unto itself. Animation too but I guess that would be harsh because the big hitters in Animation could fit in to any genre. My personal favourite is Kung Fu Panda; it's a lot more fun the the Toy Story series.
I find these things very difficult to vote on. Because there is a big difference between MY FAVOURITES and movies I think that are brilliant technically and deserve merit. Favourties can be low brow stuff too-- for example Beverly Hills Cop, Blue Streak and Home Alone would be in my all time lists because they are just so fun to watch and I've watched them a million times; but they'll never feature in any all time list.
So many great movies not included-- Kickass, Raid 2, Ip Man, Assassination of Jesse James, Casino, Apocalypto, Enter the Dragon (few more iconic movies than this). Kickass and Raid 2 are modern classics in my opinion. I don't care how new they are!
Edit: Just noticed you do have Animation:
1. The Lion King
8. Monsters, Inc.
4. Up
5. How to Train Your Dragon
2. WALL.E
7. Finding Nemo
3. Toy Story 3
6. Mary and Max
How to Train your Dragon and Finding Nemo but no Kung Fu Panda? damn. Arguably Grave of The Fireflies should feature here.
Anyway, I'll be watching how this progresses
