Sure, this movie is geared towards the younger generation, but I think that anybody can enjoy it, especially if you are a baseball fan. I don't know why people have criticized Rookie of the Year so much for being unrealistic. Duh! It's supposed to be fictional! What young kid hasn't dreamed of being a star player on a favorite pro sports team, and what Chicago Cubs fan hasn't wanted their team to go all the way? (Personally, I'm a Cleveland Indians fan, so I think you get my point.)
Yes, Daniel Stern puts in an embarrassing role as a clumsy pitching coach (now, fantasies aside, this clown wouldn't last 10 seconds as a major league coach!), and Thomas Ian Nicholas is OK in the title role but comes off as pretty annoying most of the time. I will say that Gary Busey was very good in this film as the veteran pitcher/father figure. A decent, passable sports flick.
