They're not trying to follow the game lore 100%, which isn't necessarily a bad thing. I haven't seen the movie yet though so I won't comment on whether or not it's illogical, but complaining that they deviated from the game lore is like complaining that marvel movies deviate from the comics. The most important thing is that it's a good movie first and foremost, and shaking up the story helps to keep fans of the games from getting complacent and knowing everything that's going to happen. As for whether they succeeded or not for me, I'll find out in a few weeks when I see it myself.
