Full disclosure, I love the movies and the show, but I only read classic issues of Nick Fury, Agent of S.H.I.E.L.D and classic Avengers. I never read the inhuman or Ultron stories. This review is of the perspective of the tv show fan.
Our show begins in an apartment in New York. We see a lonely woman clumsily eating a steak dinner while watching a classic movie in black and white. She is joined by Skye's father, who is always going to be Agent Cooper to me. Skye's father has brought some friends with him. We see that the woman has razor blades grafted onto the tips of her fingers. The intent is to bring down S.H.I.E.L.D because if the government and HYDRA can't one crazy guy with a dream and his dangerous, enhanced friends can.
There was a lot of interesting back and forth. One of my favorite lines was from Mockingbird. She told Simmons that they are spies and they lie for a living. This was said without irony as she and Mac have been lying to the team for months now.
Hunter is being kept by Mac. The intent seems to be to keep him safe and alive. Mockingbird tells Mac that she will arrange for an "extraction". Coulson seems to know that she not only knows where Hunter is but is keeping that information from him.
Skye's father goes on a road trip with people with enhanced abilities. They go to Bryn More Psychiatric Hospital and pick up a man whose voice puts people into comas. They then head to Wisconsin. Coulson knows this to send him a message.
The team brings a psychiatrist on the plane to interview Skye who has ties to Melinda May's past. We know nothing of May's history and this side story plays out wonderfully.
Coulson, May, Skye and Mockingbird all go to Wisconsin to confront Skye's father and his "Slicing Talons". There is a lot of action in this scene. Not the best fight sequence, but it isn't bad.
We also learn that some of the people on the "Index" are made, but some always had their powers in them laying dormant.
Skye thought that she was suppressing her new powers. Is she really? Where is Hunter being extracted too? What have Mockingbird and Mac been up to? Does Simmons try to wipe out all the Inhumans? These questions are somewhat answered.
I did enjoy the cliffhanger ending, but the agent, double agent, triple agent theme was already explored with Agent Grant. It would be nice to see the show go in a different direction before it comes as convoluted and plodding as Heroes.
