The first question you have to ask is; did you like the first one? If not, why are you reading this review? If you did, you will enjoy the sequel.
All the characters come back (via flashbacks) including those that died in the first movie like Victor and Amelia. Basically the story picks up the day after Victor was killed in the sewer and Seline and Michael are forced to flee. They are hunted by other vampires and a newer, badder head vampire.
The body count increases and new characters appear, further immersing the viewer in the storyline and plot of how vampires and werewolves came into existence in the first place.
The special effects are very good and a combination of CGI and old fashioned make-up/masks, which I found refreshing. Obviously, due to the vampire aspect of the movie, it retains the dark, gothic tone of the first movie. The acting is okay and no one really stands out, but there weren�t tons of cheesy lines like in a Mark Wahlberg movie. It is definitely more adult than the first movie, with an 18A rating because there is nudity, a sex scene and plenty of violence and gore.
All in all, it is one of the few sequels that is actually better than the original movie.
