Not bad...
Agreed, the title was rather misleading (i.e. Akuma and Scorpion were working together, rather than going 1-on-1) but overall the movie wasn't that bad, looks wise.
Scorpion was way too powered up. Considering that Sub Zero could beat HIM, and Subby could get beaten by a monk with a decent amount of martial arts skills, to put him in the same line as the dark Shotoken master dude is a bit pushing it. And having defeat Sigma's entire army (you threw a couple of MM8 masters in there too...naughty) was overkill. ;)
Good use of the sprites and backgrounds from MvC, amongst others.
Next dimension...dunno. Killer Instinct?
