For those that enjoy vampire films, you should really check out a film called Afflicted which came out in 2013. Its one of those hand held found footage style films, but it was outstanding. I know low budget films like those are coming out of the woodwork, but this is one that truly deserves your attention. The effects were outstanding and the fight scenes in the end were brilliant. I went into not having a clue what it was about and I was absolutely hooked. Definitely one of the best vampire films I have seen in some time.
As for the top 100 Vampire films, I am not sure I have even seen 100 different Vampire films.
