I gave the extra a five cause I didn't check them out. The plot isn't anything that you haven't seen before but they did it well. The majority of the characters were played great. All in all a movie you should definitly see.
This movie is definitly worth buying it has a good replay value I have had it for a month and have already watched it three different times with different friends and I could still watch it again.
What's great about it: one of the best picture qualites I have seen on blu-ray so far
