The Possessed

+ It's like an australian Buffy the Vampire slayer + decent practical FX /makeup + they probably could have made a decent TV series out of this, but not shoot it as a movie seeing how they become a ghostbusting demon-slaying team at the end.

This is indeed belongs to the comedy-horror genre, but the practical effects are absolutely stunning here! Overal it would be great as a miniseries, because each part could be a skit of its own if given time and background to develop itself and the acting would be okay for a TV-like short series where the audience and the actors are both in-on-it and don't take it all too seriously.
