Like I mentioned, I honestly kind of enjoyed it as I was able to explain away the lack of reality. What really bothered me was, I think right before it, Whistler comes out with some sort of big firearm, then just stands there while a ninja knocks it out of his hands and slaps him in the face.

Again, I explained it away to myself (vampire ninja has superspeed, standing still was just meant to demonstrate that) but, even if that was what was intended, it just wasn't very well done.
