On the surface, The Truman Show is about a man who has lived his life trapped inside of a bubble. He tries the entire movie to pop the bubble, and he eventually does.
Under that layer, though, is a complex theme. Does Truman really enjoy his cell? He seemed to for years. At the same time, he struggled with memories, but don't we all?
As the viewer, we're left to determine the morality of the happiness of millions versus the freedom of one. We're also left to consider whether Truman's cage was better than his freedom. A child born into a system that doesn't have a great track record or a life of relative safety with no knowledge of the cage.
The viewer also has to determine the sturdy nature of reality. What is reality besides our perception of it? What's real to Jim or to Bob? Are the things that are real to them real to me if I've never seen or heard about them?
Beyond the philosophical questions the movie poses, the film itself is solid. Jim Carrey pulls off the part wonderfully. He's more than just a comedian, although he can bring the humor the instant the scene needs it. The supporting cast fell right in line.
The pacing may be a little slow early on for many viewers, but that is remedied once the action begins to pick up.
If you want something light and silly, go watch something else by Carrey.
