I loved Street Fighter 2: The Animated Movie and Street Fighter Alpha: The Movie. Those are my fav game to movie conversions.
But then again I also loved FF7: AC and I liked Doom hell of a lot.
I really hope they bring out a GoW movie, and make it good not really cheesy. I mean Silent Hill was alright. Resident Evil, my god, they didnt do the games any honour there. I mean they basically gave the game a bad name, shat on its grave, dug it up, mummified it, burned it then shat on it again. Too much action, too much change in the storyline, not enough of the survival horror atmosphere. Thats my opinion anyway.
