They are cartoons, and they play basketball with Michael Jordan to save the earth. I do not remember the quality of the animation, and it is no Who Framed Roger Rabbit, but, come on. It's Space Jam.
The good bit is the shot-for-shot remake of that old Bigfoot video, this time with an alien. You can find that on youtube, so there's no reason to watch this movie.
A heartwarming tale of a chicken who dreams of being president. Well, not really. Pretty much these chickens just want to be "somewhere else" and hope that this will solve their problems.
I would advise watching it in Japanese without subtitles. That way the vocals will sync up with the characters mouths, and you won't be worried about the plot/writing.
Robert de Niro and that blonde chick from Man on Fire are involved in some kind of thing and then there's a bit in a cave and then it's the end of the movie.
These people go underwater and there is something down there that they don't understand anyway they go back up to the surface and it's all better again.
