Has the ever been a good video game movie adaptation?
Doom is really good. It follows the events fairly well to a degree. Other than the overdropping of the F Bomb, there's nothing wrong with it.
The Sonic OVA is another great one, based upon Sonic CD but adding its own characters to change it up a bit. Seems influenced by Sonic SATAM, as Eggman has a robotic form, and a Metal Robotnik form.
Street Fighter II has its own anime movie. That was another good one.
Another is the Fatal Fury movies. Those all did a great job.
The Darkstalker OVA is a really good adaption. Though it had an issue with a poor handling of a ton of characters as is. It might've done better if it was longer or had less to work with. It's odd to say, but the Darlkstalkers cartoon actually did a better job at making each character feel relevant and not just a cameo/afterthought. A terrible(but fun) cartoon, though.
The Tomb Raider movies are really good for what they do. Maybe not the most perfect, but they capture the feel of the series well.
It should be noted most take some liberties to change it a bit. Also, the Pokemon movies are mostly good on their own merits(though not adaptions, but just saying). I mean the Anime ones as I haven't seen the live action one. Only thing I'll mention about the first Mortal Kombat movie is that it did get the feeling of the series down overall while doing a pretty reasonable job of being accurate. Not perfect. Only the second movie was trash(fun trash, but trash), and that was a similar issue to the Darkstalkers OVA. Too many characters and couldn't do anything with them.
