I haven't seen the new Al Gore movie, but I'm pretty sure I liked the original better.
Although, I'll say this: Straight one-to-one remakes are always a mistake (did you know that they've redone The Omen?). If you're going to remake a movie, you have to do something different and interesting. Remaking fiction as a documentary is a pretty neat idea.
It's not an original idea, of course. The Discovery Channel remade Perfect Storm as Deadliest Catch. The new season looks pretty great, actually.
Maybe Gore should have used Bon Jovi in his trailer.
