Query: Very entertaining/thoughtprovoking

The title says it all. Very well crafted movie. And a note to a previus reviewer who said that Carrey turns to the camera and says nothing at all - this is not his fault, it is yours for not picking up on it. The reason he does this is for dramatic effect. He can't see the cameras, but he can just sense something.. like something's not right. Sort of like "What is the Matrix?". Anyhow, Jim at his best here definitely, and the supporting characters fit well.
