I noticed it started and ended without accomplishing anything, it just went over a singular small event that wouldn't even fit a movie format. Then I realized it was a drama that was cancelled. Regardless of the cancellation, I didn't see anything appealing or interesting in these two 70-min episodes. These possessed creatures were your generic screechy zombies with no life in them, no pun intended. The drama didn't provide a good introduction to set up the story or a good introduction to establish the characters in these two episodes, which should have been an enough duration to do both things easily. It got cancelled but at least the cast got paid.
