I'm gonna throw myself to the lions and say that both the first Mortal Kombat movie and the Street Fighter movie were good films. Well, not so much on Street Fighter, but Mortal Kombat managed to hit the essence of it, had good fight choreography, good actors, and a simple, but good enough plot. It's not Oscar material, but it's at least FUN and it does nail some aspects of the games well. Street Fighter: The Movie, may not have as excellent fight choreography, though when you compare to the cinematic abortion that was The Legend of Chun-Li, it's practically Citizen Kane. Bison is ludicrous and fun (thanks Raul Julia), Jean Claude Van Damme is just hilarious as Guile, and Ryu and Ken's subplot with Vega and Sagat wasn't so bad. Yes they fucked up with Dhalsim and Blanka, but in the end, it was pretty enjoyable, regardless of what the Nostalgia Critic says. And I'm willing to go out on a limb and say that the upcoming Prince of Persia: The Sands of Time movie will be good, because of these reasons:
1. BUDGET. They've got Jerry Bruckheimer/Disney backing it. IT WILL LOOK PRETTY.
2. CAST. Jake Gyllenhaal and Ben Kingsley. You've got Donnie Darko and fucking GANDHI. And also, Alfred Molina. Donnie Darko, Doctor Octopus, and GANDHI are in this movie.
3. MUSIC. Harry Gregson-Williams is composing the score. FRICKING METAL GEAR SOLID'S (and Narnia's) COMPOSER IS COMPOSING THE SCORE.
4. Jordan Mechner, the original creator, had a heavy hand in development.
5. For stunts, they got the FOUNDER OF PARKOUR to choreograph.
Pretty much, PoP, Mortal Kombat 1, and Street Fighter will probably be the best video game movies. Unless Resident Evil: Afterlife manages to not suck (which it won't, even with James Cameron's megacamera)
