I really liked the first one and was hoping they wouldn't mess up this sequel. I was pretty happy during the first 2/3 of the movie, as the plot and various storylines were interesting and well managed, in a way that didn't feel like re-heating the formula from the first movie. Unfortunately, they tried so hard to keep the originality going that they went completely overboard with the denouement, and the whole thing feels quite silly when it's all over. Which seems to be pretty much the general opinion about this movie. So all in all it's fairly entertaining and I would say go for it if you have ran out of things to watch.
