Yes, I liked the first movie alot as well, even the second.
Personally, I would rather have known going in that it was not "supernatural" and was just a "trick". That's just me though
I try to put myself in a particular frame of mind for the movie I go too. For example, I don't go to a Jackie Chan movie for the deep story, so I am a bit more lenient in terms of story. So for a movie that I am expecting to be a "sci-fi, horror" and it turns out to be something else, it dissappoints me a bit since I am not in the frame of mind for that particular type of movie.
