I found this one to be a very pleasant surprise. There were genuinely some very creepy moments in the film, which seems rare in horror these days. If it holds up as well on a second viewing, I might just say I loved it. And it looked like a far bigger budgeted film than it was apparently filmed for.
Yeah, it did seem like a blatant ripoff of Poltergeist at times, but it did have enough originality to set it apart.
The Blu-ray transfer has excellent A/V quality too.
