This movie is nothing more than another entry in a franchise that has made it's entire existence during the month of January because they know that there is nothing else out there. The funniest part of this movie is that they had to do a "previously on" type of segment to remind us viewers what the story was from parts 1 and 2 since the last entry had nothing to do with it at all. Like I said - it's just more of the same. There are vampires. There are Lycans (aka - werewolves). They fight each other and the humans. The end.
If you like the first two entries - this is just as watchable. If you didn't or didn't see them - why in the world would you start watching these now?
