movie adaptations of video games: why always diff. from the org. product?

[alvarado52]

Really though. Im a gamer for sure, have been since i was a wee pup, but the thing that gets me is...why do movie producers, etc. feel that they need to stray away from the game. They always have the same title of the game, they always pick the most popular games that ANYONE would recognize, yet they completly change the story or alter it to 'hollywood' the storyline. The thing that really comes into mind is Resident Evil. I think the story from the game(s) is a pretty solid one, and would make a damn creepy movie (especially the 1st one, being in a big ass mansion in the middle of nowhere!). Doom stayed pretty good with the story, it wasnt connected to the games, but i feel they kept enough elements there to keep it close. Dont get me started on Alone in the Dark though, i wont be watching that OR BloodRayne cuz they put the same dipshit in the helm of both of them. Hopefully Silent Hill doesnt disappoint. Wow, i just ranted.
