Plot hole: What happened to the two boys who stayed in the museum past closing, after the homeless guy seemed to attack (or at least be seen to be stalking) them? The next time we see them, it's the next morning, and they're fine. So where did they go? Who helped them? What happened to the homeless guy? The boys couldn't have just hidden, as the homeless guy has been in the museum for ages, and these two boys just got there that day. The homeless guy would have known all the nooks and crannies and every little hiding spot available; he would have caught them.
