I watched it last night. Yeah the movie is pretty typical until the last 20 minutes. Then it gets menacing.



*SPOILER*









I appreciate movies that switch it up like this. 2/3 of the movie is stuff we've all seen many, many times before. Then it takes that sharp left turn when you see that those kids were not going to Scooby Doo their way out of it. By the end they were in way over their heads, and there were consequences. We don't often get endings like that.
