One of the best movies I've ever seen and definitely THE very best happy-ending-movie! That means something, cause I consider movies being my hobby and I've seen quite a few (not really into books). Justice is served finally and totally. Yet it doesn't make the movie seem like most of the other movies in the happy-ending-genre. The film was all action without much action. Not a moment where the story doesn't progress. It is very different from the first two, and dare I say, in a good way. I find this to be the only movie trilogy I've seen where the final movie is actually the best. I found myself loving the movie on many occasions. If you've seen the first two this is a must. If not, watch them first and then come back for this one. It's worth it!
