Quickly: not bad, pretty good animation but very cartoony, Fish was awesome.
Summary: Disney's bizzar take on the Chicken Little story. Something falls from the sky, no one believes it, kids tramautized. He is just starting to get over it with the help of his friends when it happens again. It's not the sky it's aliens! Aliens attack, kid saves the day. That's basically it.
The Good: Fish is awesome. I would love a movie just staring one character, actually I watched the movie twice in a row, one time all the way through, the second time just watching the scenes with Fish. The story wasn't as predictable as expected. The visual effects were rather cool, with some damn nice 3d art. The characters were over the top in a good way, and I especially liked the fact that they acted somewhat like their real life animal counterparts. I liked the fact that little looked like your usual cute geeky kid with glases but didn't act like it. He actually had a bit of Pro in him, and had an attitude, that was a nice change from the ubergeek character I expected.
The Bad: The story was still pretty predictable, though that was to be expected. Some of the visual effects were just too cartoony. I know it was done on purpose, but watching talking animals run around and fight aliens is funny enough, they didn't have to add the cartoon physics.
The Ugly: The caracters looked way too much like something out of Richard Scarry. There are a few scenes that are so cute they are ugly. The alien baby was just a bit too much for me. I could not stand the Runt character. The way he looked was just so overdone it was dumb, his lines were 99.9% groaners, and not in a good way, and his voice drove me nuts.
Overall: really not bad. Better then I expected and I actually laughed out loud a few times. I also groaned quite a bit as well. It was worth seeing, if only for Fish.
