If you played Warcraft, you will probably like this movie. It certainly isn't it he best movie I have seen this year.
In my experience most critics can't ever sit down and just enjoy a movie. While some of there reviews do line up with user reviews on whether the movie is even watchable, this is not the case here. In my opinion the movie is worth watching on the big screen. Could it have been done better...certainly. Go see the movie and decide for yourselves! :)
