They r filler episodes. Important to the story line. Seeing as the tv series isnt following the comics all the more important.
I personally have enjoyed the last couple episodes. Character building. Also, leading up to something big. Wont spoil it.
FYI the show is kicking arse in the ratings. Always a plus cause that means the show is in no danger of being cancelled.
3 more episodes to go, you will all be satisfied, just wait and see.
