Gamertell has posted an opinion piece about games that make good movies.
From the article:
"There's a pattern though, found among the more successful video game movie adaptations. Look at the Resident Evil, Tomb Raider or Silent Hill movies. What do all three of these movies have in common? Not female protagonists, though that is a common tie. All three movies or movie series don't strictly follow the game. Instead, they follow the spirit of the games."
