Killjoy 1 and 2 were... not... great. But the series does get better! On the one hand, how could it not? On the other hand, Killjoy 2 answered that question.
Killjoy 3 however, has an actual budget (albeit a miniscule one) and tries to maintain some level of logical consistency with it's supernatural storytelling. Is it good? Well... I mean... it beats Killjoy 1 and 2.
