Before watching the movie:
This concept is hardly new to me, but I don’t know if it was new at the time or not. Rodney Dangerfield’s character goes back to school and embarrasses his son by being his classmate. It seems to me that the 1980s would be a time when adults were faced with re-entering education, since the changing markets would shut down factories and force people to get better degrees.
Anyway, in the films I’m familiar with (Billy Madison, An Extremely Goofy Movie) have extenuating circumstances forcing the adult back into school. In the latter case, Adam Sandler has to get a high school diploma within a few months or he won’t inherit his father’s riches, and in the latter, Goofy gets laid off and doesn’t have a college degree. In this case, it appears that Dangerfield’s character is simply wealthy and has nothing better to do than go out for some higher education. That’s fine if it plays well.
Also, supporting actors: Robert Downey jr. when he was a young heartthrob! Robert Picardo in a minor role! Kurt Vonnegut in a cameo! (I’ve never seen the man in motion)
I don’t expect to have to hold this film to a high standard, because it’s clearly intended to be a fun popcorn movie vehicle for Dangerfield.
