I continue to be amazed that the guy from WKUK is this good at making movies. Look, this is the weakest of his three horror features and it is still an excellent movie. In comparison with Weapons and Barbarian, it is significantly more straight forward in terms of plot.
That said, it does a really nice job of following the video game model of jumping from scene to scene, living in that location, and then moving on. There are a lot of nice video game nods and a few very funny moments, but movie doesn't get lost in the humor as it is, fist and foremost, a horror/adventure.
One thing this movie does that kills a lot of game adaptions is it dances around the boss fights. The "boss" is alluded to, seen, and acknowledged, but never directly addressed because very rarely does a boss fight translate well to a film experience in a movie like this.
I'll also mention that Abrams does a fantastic job of carrying the load as Bryan.
