It's based on a game and it shows.

Rating: 3/10 (23 October 2016)

If you play battle games you may enjoy this. It is based on a game but somehow people rate this as good for a film.
I don't rate it at all. There is no real storyline and the characters are 2d. Basically actors walk around a cgi set and technicians do the effects. There is no acting and there are no characters. The roles are very cardboard cutout with no personality and no subtlety or humour.
So if you are 14 and male you may enjoy it as a film. If you love the game you may enjoy it. However, if you don't then it's doubtful.
Ignore reviews from other people comparing it to Lord of The Rings and GOT. You would be better comparing it with Noddy and Bigears go to War. There is no comparison with either as there is no storyline and there are no characters. Oh, I guess there are orcs. Thats really the only similarity.
