I liked this more than I should have.
I have tried the games, but am not into the fighting genre of games (although the Injustice series grabbed me for its story). The previous movies were fun and didnt take themselves seriously - which was good, but they got too hammy and over the top. The last cartoon took itself way to seriously and was disappointing and forgettable to say the least.
This movie, however seemed to grab everything good from the previous attempts, added actors who know some martial arts, used some of the key terms and moves from the games and had a stand out performance from Josh Lawson as Kano adding the 'very dry type of Australian' humour. Hell, the score was even good.
Given that this is pretty much the same as the game - 10-12 fights some spectacular fatalities and a basic plot with no character development - this was a very fun way to spend 2 hours.
