2 sucked but 3 was pretty good. I'd recommend watching both just so you can see the entire trilogy.
I also loved the first one but have been hesitant to see the sequels. I'll probably end up watching them eventually.
The first one was great though. I loved how it seems like a typical crime movie until about halfway through when you suddenly realize it's about fighting vampires.
The 2nd film looks like it was made for TV, however the third film was a nice surprise. Michael Parks (who played in KILL BILL: VOLUMES 1 & 2, FROM DUSK 'TILL DAWN and GRINDHOUSE) stars in it so I was glad to be able to see more of his work. Also, it's a prequel and takes place during the old west. A good pick up if anything factors interest you.
