The parts of this movie that you want to see (the "equalizing" if you will) are very enjoyable and great. The problem is that there is ALOT of this movie where he is not getting revenge on the scum of the earth. Those parts drag to no end and really weigh this movie down. If this was a 90 minute movie or less I would have loved it. Two hours and 10 minutes? No need for that at all!
I wouldn't really recommend people bothering with this. It's a sequel that really did not need to be made and should have been majorly shorter and to the point than it was.
