I was not impressed. Phil didn't seem cool to me. The two young science agents annoyed me. The hacker girl, Sky, wasn't interesting and her cleavage shot was cheap. The straight guy agent could be okay if the show revolved around him and Ming-Na Wen's character who was the only one I found interesting.
Oh, the Helicar was dumb.
Also, the mystery bad guys using alien, Supersoldier, gamma radiation and Extremis was overkill, at least for the first episode.
On the plus side, the nods to the movies was kinda cool. The mystery of Coulson's trip to Tahiti is interesting. (I once heard a theory that Coulson was actually the Vision.)
Will watch again, but happy I went in reasonable expectations.
