Blame the distributors for not making more episodes available to critics for review. The most famous case of this is Bojack Horseman. Netflix sent out the first six episodes before the show aired and those are pretty meh episodes. It took a BIG creative leap in the second half of the season. There were critics who when the show came out kept watching and said as much. But if Netflix had supplied them with those eps to begin with, the reviews would have been a lot better.
