As a movie this is a very good movie. The scenery, the acting, the colors etc. are of a very high technical standard. To me personally however, this movie is much too dark and depressing for my taste.
I cannot say that I am surprised that the movie is dark. The first movie was a rather dark one after all and this one is a truly post-apocalyptic one. I quite liked the first movie despite its dark setting though. However this one takes the darkness and melancholy to an entirely new level.
As I said before, technically the movie is great. The scenery is stunning whether it is a dirty little hut out in the badlands or the equally dirty vast cityscapes. The scenes of the abandoned city where Decker is (re)introduced is sad but beautiful.
The acting is more or less great from all the main characters and the special effects are very well done and just right to fit with the rest of the movie.
Unfortunately I cannot bring myself to give it more than 3 out of 5 stars. It has nothing to do with the quality of the film but a lot to do with my personal taste which of course is reflected in my ratings.
