Working Titles

  • [no known working titles]


The level of not caring is so apparent from the writing to the acting to the plot to everything. Nothing makes sense and what does come up is very, very confusing beyond all belief. There are so many cringeworthy and horrific acting and characters it is astounding, the episode is very easy to forget. There are a couple of nice effects but other than that this episode should not be on anyone’s watch list in the foreseeable future. *​



Number of Production Days: 5
