I'm not gonna offer an opinion on Chavez. I think both he and the situation in his country are immensely complex and not fully understood by most. All I would suggest is that you watch the documentary "The Revolution Will Not Be Televised" AKA "Chavez : Inside the Coup". When making opinions, it's best to gather as much information as possible to add context, and I think that this film adds an important piece of context.
