Story: As great as the first movie! If you've seen that then you should definately see this. If you haven't seen the first movie then watch that one before you watch this one.
Acting: Mostly the same actors as the first movie. I love Erika Toda and she did a fantastic job in this movie! (as one would already suspect).
Music: Same level as the first movie.
Overall: Really good! Watch it (after the first movie that is).
