Just from watching the trailers the Haunting seemed all right.  The kid ghosts seem kind of chintzy but the overall set-up seems all right so maybe I'll check it out. 

Those particular spirits are by no means the main horrors of the film, fwiw.

Out of all the trailers the one that I couldn't really get a bead on was the Grimm Love trailer...  It could be rather tepid (the main character better have a motivation for fixating on a past killer otherwise the whole thing wouldn't make sense); however,  if it's filled in with some substance and good narration maybe this could turn out pretty good.

Let's just say that your concerns are well-placed.
