The original is one of the best films ever made. That said, I LOVE Zombie and his movies. His remake is easily the best remake since the days of the Fly and the Blob.
I am very excited about this movie. Originally, the guys behind the excellent Inside (you seen that one Mercedez? It is a SUCH a great movie!!!!!) were slated to direct this. But, disagreements occurred, or something not sure what it really was, and Zombie is back.
I think he will pull off a killer movie. And, yes Michael cannot and will not die!
I heard about the Let the Right One In, but ain't seen it, yet. I don't think this one is available in the US, yet.
