This is that kind of series that go in a crescendo. At the beginning it was kind of slow, with an episode-based story, mostly on S.H.I.E.L.D. (God, that is tiresome to write) agents working. Then a bigger story is formed, curiously, joining some of the different stories that were told before. At the end, a big crescendo and a great season finale.
The, you have action, your have scifi (a lot), you have girls for every taste, and a lot of humor. And if that is not enough, you have Skye, a sexy… erm… E.T.
