Yeah, I’ve seen that video a few times. I’ve heard anecdotes that people could cut cinder blocks with the ‘replica’ Daywalker sword, although I doubt that very much. But I can carve cardboard up quite nicely. So if the zombies are corrugated, I’m set.
The real problem for me with that one was that normal humans were so bad ass. How the hell did Ryan Reynolds manage to not get pulled into pieces 5 seconds after confronting a vampire? He was just a human being, after all.
