I'm not asking for it to be high explosive action films, nor super slow for the whole film. Build up the suspense. These games do have atmosphere. Hell, look at the remakes for 1 & 2. The film adaption for 1 can have a few action moments, and it can work fine. 2 & 3 especially would just be an action horror. It would have a great blend of horror and action. You start with the horror and then you slowly build up to the action. The finale of Resident Evil 2 is just basically Aliens. Resident Evil 3 is literally the Terminator combined with Dawn of the Dead. That one would be the most action focused when put in film too. And all of them can be scary while doing it.See that's my sticking point. In order to make a Resident Evil movie that's a slow paced horror movie, you have to "adapt" it so much its not Resident Evil anymore. You can't do the giant set pieces, the giant monsters, the action scenes, the goofy dialogue, the international bio-terrorist groups. You have to stick to spooky empty hallways, slow moving groaning zombies, individuals with only a handful of rounds, and no way out of a spooky place.
And at that point, if you want to do the slow paced horror movie you're limited to the first game, the first mansion of the first game, the first floor of the first mansion, and the first 10 or so hallways within the first floor.
After say the first half an hour Resident Evil its no longer the slow paced horror game but an action set-piece adventure game with puzzle elements and zombies are more road hazards than legitimate threats. And that's before the giant spiders, giant snakes, zombie sharks, and magical tree witches, and that is before the bio-titans with swollen eyeballs and cheesy one-liners and ALL of that is before fighting a giant fly in downtown Hong Kong with a rocket launcher.
And I love Resident Evil games. Loved 1, 2, 3, 0, 4, 6, Outbreak I and II, hell I even liked Dead Aim. But these are not slow paced subtle games, they're high flying action games more akin to Duke Nukem than Silent Hill.
All of these games I mentioned can be adapted properly. They all don't have to have a Michael Bay explosion level of action fest. Aside from maybe 3, but that's just being generous. Then again, the city actually does get nuked.
