As with most horror genre films, "good/bad" is subjective. Frankly, I'm an easy audience in that section, I'll usually enjoy even "bad" films that claim to be horror.
I found this mediocre, at best.
It started out ok, if a bit slow. The cat wasn't "scary" in the slightest, looked like a cat with jelly smeared on it. The first person to "return" was done well, actually a bit disturbing.... But then it quickly devolves, rushes through the ending, and finished like a bad TV episode.
Not impressed.
