I do not know what was being attempted by this movie. If it is a parody, then it drastically needs humor. Bill Murray's character Zissou is an empty shell of a person who really doesn't care about anything, not even money or greed like Royal Tannenbaum. It is hard for me to see any resemblance to film maker Cousteau. Most of the characters are as one-sided as paper dolls. Owen Wilson's Ned is the only one who seems to have any blood pulsing through his veins. Basically, this movie is a vapid cartoon.
Actual aquatic life is wonderful. Why does this movie want to adorn fish with finger paints and rhinestones ? How depressing !!!
