Although seasoned horror viewers won't have much difficulty guessing most of them, there's still a good bit of fun to be had.

Séance's climactic sequence is so wild, so gory (some practical effects and giallo influence go a long way), and so knowingly funny that it's almost as if [Simon] Barrett is apologising for keeping things rather calmative to this point

Not a riff on slasher, nor an homage, but a straight up repetition, complete with all the banalities therein.
