A late review... i watched the series as it was airing and it was a whole lot of fun.
The whodunit kept me curious and hooked! I don't understand the negative reviews.

Were the characters good? Nope
See it's a matter of survival and thats brought out the worst in all of them. Humans have animalistic instincts after all. So we should've expect to be able to relate to that simply cuz we haven't been in that situation. But portrayed well and it makes perfect sense.

The ending gives closure while leaving room for season 2. Was it the best possible ending? Maybe
Well compared to other supernatural options this was better.

There's quite some gore so not for the ones scared at the sight of blood.
