Even there were only few special effects they were brilliant. They are; when they needed to make Edward shiny, when they make him run fast and when he glides from tree to tree. And there was an extra special effect they used for when the bad vampires entered in the baseball scene. This is what makes them look like they're walking faster than they really are. The name of the effect was called "Magic Carpet".
In my opinion I think this movie can be entertained by people of all ages. Before I watched this movie all I thought was this movie is a boring movie. However while I was watching the movie, the movie proved me that its not boring anymore. I think this is one of the best films I've ever watched.
