I feel like the problem is that filmmakers dive into these projects without knowing anything about the games they're based on. That was more than apparent with Warcraft, so as a huge fan of the series and WoW, the movie was painful to watch. Same thing with Assassin's Creed... nobody who has played the game would have kept the Animas idea, and if they did, it sure as hell wouldn't have been a central focus, constantly shifting back and forth. That's what everyone hates about the games!
