El Cuco

As always, no pun intended - and as you may be able to tell (especially after watching the movie and if you have seen a few horror movies like I have), you very likely will agree. Not everything needs explanation, actually the movie lays and serves everything right up for the viewer to enjoy.

Is some of the behavior questionable to put it mildly? Yes, but you have to have some suspension of disbelief ... otherwise nothing is possible and/or plausible. Would I just leave my home to anyone? Not really, but again you can't start with thoughts like that ... the rest explains itself and is easy to follow.

What's the overall history? Do you really need to know? I think the movie reveals as much as is necessary ... the acting is great, the cinematography is really good too ... and the script is more than decent enough itself ... there is more to life ... but sometimes also less to it! The door closes opens kind of thing ... doesn't have to be the same room/person, right? Well you'll see ...
