To be fair, no one entered the last one until the 15th of June so I'm not worried as of yet. In fact, most of the entries were entered in the last week of the competition. I guess people wanted time to get them just right and such. Be patient, my dear Gavin! :D
Also, the reason for it being episodic reviews rather than that of a season or a whole series is that one can get into the nitty-gritty of what worked/didn't work without turning the review into a PhD thesis or something. To do a whole series review in the space of 1500 words would be to do a very surface-level appreciation/evisceration, but for an episode, it works quite well. TV episodic criticism is also my favourite type of criticism, so I guess it has a special place in my heart as well.
