The movie is not perfect but having been surprised after googling its
budget ,its done a pretty good job.
The CGI was great and most action sequences were entertaining. Acting could have been better and the screenplay seemed too rushed that every 15 minutes we are left wondering if what just happened had any past to it which we accidentally slept through. Raiden's accent was kind of off and weird .There are a LOT of plot holes so I wouldn't recommend going in with the kind of critical attitude.
Scorpion and Sub-Zero were the best parts of the movie. The actors did a great job. The CGI was perfect and their back story was really flushed out too.
Pros: Scorpion ,Subzero, Visual effects, most of the action, gore
Cons :Acting of some actors , Story ,Screenplay .
Though it was just the first movie ,felt instead of introducing a hell lot of people altogether they could have done with some of them but really work better on their backstories .
