This episode is loads of fun, for any fan of the show having "the band back together" is bitter sweet, there is a scene in this episode with everyone around a table that is full of tension and so well written and acted, there is also a long shot fight scene that is exquisite.
One thing I didn't like about the episode is the Age of ultron setup, the MCU fan in my ate it up, but looking back it just doesn't flaw naturally, I wish they would have cut Raina's vision, it serves no purpose on the show, Theta protocol though worked as part of the show and the movie so i would have been ok if it was the only connection.
