You get a free digital rental of the movie if you pre-order MK9 from Amazon. I checked it out through that promotion, and although it was kind of bad, I still had fun. And it was free. And legal. Just saying.
 
EDIT: Actually, looks like that might be over. Oh well.

Best thing about those films was the theme song playing during the credits.

MK remains pretty much the only all-good videogame movie because, let's face it, the game is pretty much a kung-fu movie...so they just went and made a kung-fu movie. They didn't try to change everything around (Street Fighter, Super Mario Bros) or try to cram everything that's good about the game into a plot that can't support it (Silent Hill). And it was by people who actually seemed to care whether or not the product was any good as opposed to just being a cheap cash-in (Legend of Chun-Li, anything Uwe Boll touches). 
And sadly, to your point of the 3rd movie, it's by the same people who did the 2nd one, and they're the ones holding back any kind of progress with the series (hence why Mortal Kombat: Rebirth is a web-series instead of a full-on movie). Oh and as a bit of trivia, since you like Kano so much, Ed Boon and Co. liked his performance so much that they actually had him be Kano in future iterations. Not this most recent one, though, as I believe he's dead.

One thing that did bother me though was Scorpion and Sub-Zero being mind slaves. They are the two biggest mascots for the games, and though I understand wanting to make the movie about the good guys, I didn't like that they were made lame like that and worked together instead of fighting each other. It would have complicated things, but it would have been cool to see them get a proper subplot as real characters. Though that would probably require some level of actual film making skill to pull off.

It comes out on Bluray the same day as the game. 
 
Also, Sub Zero totally gets killed by a bucket. I mean, what the hell.

It always bothered me that Raiden was made into a white guy. Raiden from the video games is so obviously asian. Also, I don't understand how Scorpion's rope+knife-thingy was interpreted as a creature living within his hand. Not that rope-knife-combo makes a whole lot of sense either (such a weapon could never be used in the way it is in the video games, as the knife would simply slide out when the rope is pulled), but that's clearly what it's supposed to be.

" It always bothered me that Raiden was made into a white guy. Raiden from the video games is so obviously asian. "

Johnny Cage vs Scorpion in the first MK movie is one of my favorite  scenes in an American martial arts movie. 
It just has a certain je neis sais quoi visually and performance wise. 
And they really did an impressive job with the Goro animatronics.

I rewatched it fairly recently. Mortal Kombat was one of my all time favorite movies as a kid, so my memories of it were quite fond. It held up somewhat decently, although at times it felt really disjointed and some of the scenes where unbearably corny. Christopher Lamber's performance as Raiden is... odd. Still, the fights are great and it stays close to the source material, which is corny as hell in it's own right. Still the best videogame movie to date.
