I saw this film at the cinema the same day as I saw Lost in Space (the new one, with Gary Oldman). By comparison, Lost in Space was high art full of deep metaphysical dilemmas. MK:A is terrible.
I loved the Mortal Kombat games, and was pleased to see that MK The Movie was better than Street Fighter II The Movie. Sure, it was a light-on film, but it had some moments and I spent most of my time laughing at the unintentionally bad bits. MK:A makes MK The Movie look sophisticated.
The first five minutes basically drops a piano on the head of the first movie - new bad guy, Johnny Cage dies, new heroes appear, minimal explanation. From then on you have a sub-standard martial arts film packed full of cheap costumes on cheap actors following a cliched script. I know there's not a lot of narrative you can squeeze out of a fighting computer game, but surely the writers could have tried a little harder to make something work. Having gone to the movie with a guy who didn't play the games, I had to explain what the hell was going on for the first half (like why is that guy fighting him?) and gave up after that.
That said, this movie contains the most unintentionally hilarious moment I have ever seen on film. Towards the end of the movie, Raiden moves from having flowing straight white hair to a peroxided flat-top. There's a brief mention of Raiden getting a haircut, and that's it. It makes absolutely no sense, and thinking about it still makes me laugh.
