Here's my thing with Pixar movies.
Toy Story = Loved it, because I was little when it came out. I still like it. 8/10
A Bug's Life = Didn't really care about it. So I didn't really absorb it, though it's okay now. 5/10
Toy Story 2 = Didn't like it, because my little asshole cousin annoyed the shit out of my with Buzz Lightyear crap. As an adult, I fairly enjoy it. 6/10
Monsters, Inc = Didn't care enough to sit through the whole thing. It might have been good, but I just really didn't care. 2/10
Finding Nemo = Loved it, and still think it's good, but having to watch it all of the time ruined it. I watched it at school, grandparents, home, field trips, and camp. 6/10
The Incredibles = I didn't like it at first, but I've warmed up to it. I think part of what kills it for me is Jason Lee, I just think he's pretty useless as an actor. 7/10
Cars = Hated it, still hate it. It just isn't really focused, and isn't engaging or cute. I can't see how anybody else liked it. It bores me. 1/10
Ratatouille = Favorite Pixar film of all time. This movie is so beautiful, and well thought out. It's cute enough for the kids, and deep enough for adults. It's the perfect story of acceptance. 10/10
WALL-E = This movie is incredibly beautiful, and very interesting. I just wish it would go further. If a decent sequel is made, I will revoke my minor fusses with it. 8/10
UP = I like it for what it is. I agree that the beginning is what sells the film. Moments actually caused some stinging in my eyes and a lump in my throat. I think the film becomes boring around the time they run into Charles Munce. 5.5/10
Toy Story 3 = If there was ever a movie that deserved it's praise, this is one of them. I loved every moment, and I did nearly cry, had I not been around family, I would have. It was a far better sequel than 2. Though some of the emotional moments made me laugh, like the "Your momma don't want you!" moment. It came off as cliche. 9/10
Rating scale is based on Pixar, not overall cinema.
