I've known 5 year old kids who play Mortal Kombat, and they're not out chopping people up and ripping out their spines or anything like that, as the review seems to think. It does depend on the parents - my mom is totally fine with all the violence, and actually finds that quite interesting.
Anyway, on to my review, which is a lot more laid back.
For all the good stuff (positive messages and role models), I'd say there are plenty of good natured characters, seeing as how most of them are attempting to stop Shao Kahn from taking over Earthrealm. They don't even really kill people in the story mode - most of the time you're just defeating the opponent and leaving it at that. There are deaths, but all of them are in cutscenes.
The controls are quite easy if you can remember the attacks; meaning you'll probably pick just one character and want to stick with them, rather than having 5 characters and forgetting their combos once in a while (but if you can remember all their moves, hey, go for it). The Fatalities are also pretty easy to perform - especially if you have an online guide and can just look up exactly how to do it, plus the game is nice enough to give you plenty of time to perform it.
Obviously, this game has en excessive amount of blood and gore - heads will roll, bodies will get ripped in half like a wishbone, and they tend to explode from the inside pretty often. Of course, all of this is pretty entertaining, but not for the weak-stomached (but if you're like that, I doubt you would be playing this game anyway, so that all should be good).
The females often wear exposing outfits; but nothing bad is shown. The worst you'll see is a butt or so, but everything else is covered.
I honestly can't think of a time when someone cursed - I'm probably wrong on that, but I haven't heard one F - bomb at all. There's an occational 'D***' and 'H***', but even so there's not that much.
Overall, this is an amazing game. The storyline is fantastic, the character models are awesome, and the Fatalities are as brutal as ever. You must play this game - even if you're not a fan of fighting games. I can guarantee you'll find something out of it. I give it 5 stars. Flawless Victory.
