I don't know what to think about this. Where I live, you can buy the Japanese film, so I don't really think I'd ever want to watch a remake. That's not because American = bad, it's just that I've seen Battle Royale already. It was good, and I don't feel the need to see the same story again, with different actors.

If you have to see the second one, watch the director's cut, Battle Royale II: REVENGE. It's still a crappy movie, but better than the theatrical cut.
