Just got back from seeing it - surprisingly it was a very varied audience. Everyone from seniors, to parents with kids, to teenagers. All of 'em clapped at the end.
Personally, I was a little dissapointed in it. Make no mistake - I thought it was a quality movie, but overall, I felt it was slightly on the bland side.
First off, the good points. I really liked the heart of the story - a father and his son and their love for each other. In a sense, I thought this has the most heart of any Pixar film because its quite intimate and very relatable. I liked most every character, and most of them provided some good laughs.
Now the bad: I didn't feel the story itself really warranted a 1 hour & 40 minute run-time. I thought there were a lot of scenes in there that could have been trimmed out. One thing I like about Pixar's other films is that they always seem lean and reletively quickly paced - I thought this one dragged in several spots, just alternating between the father's swim across the ocean, and Nemo's experiences in the fish tank.
Looking back on it, it just seems like the whole thing was a series of events strun together to create a movie. Heck, even the events of the climax had nothing to do with the rest of the film.
Anyways, overall, it was a solid film for both s and kids. All in the theater seemed to enjoy it.
My favorite dialogue:
"Don't you realize we're swimming in our own sh-"
"He's trying to speak to me, I know it!"
"Heeeere's Brucyyyyyy!"
Here's how I'd rank the Pixar films till now:
1. Toy Story 2 (9/10)
2. Monsters Inc. (8/10)
3. Toy Story (8/10)
4. A Bug's Life (7/10)
5. Finding Nemo (7/10)
