Having a double without sharing experiences is not cool.

This is terrible. Michael Keaton's character is a real monster. And I'm not talking about his clones. The main character. Total jerk.

A good movie with an interesting story concept that, although well-explored, could have been developed even further. The film has some problematic aspects by today's standards, but this is a minor issue. Michael Keaton's performance is excellent, convincingly portraying different roles and conveying the idea that, despite the differences, they are the same person.

I always found it charming and Michael Keaton is pretty good playing 4 different characters. Harold Ramis has made better but also far worse, like Year One.
