We watched "Shark Tale" on DVD tonight. It was amusing, but as a NY Times Review says, it's "pop confection".
Nowadays big stars play the parts of the animated characters, and
their personalities are part of the animated facial expressions. This
film has some big names: Robert Di Nero, Will Smith, Renee Zellweger,
Angelina Jolie, Martin Scorsese, and Jack Black.
If you have to chose between this movie and "Finding Nemo", I would recommend Nemo.
