I have been anticipating this show for quite some time now, and my expectations were high. Let me start out by saying that I am a big Marvel and Avengers fan, so there was no question for me whether to watch this show or not. The fact that Clark Gregg (plays Phil Coulson) was in the cast only heightened my expectations and excitement! The pilot was, in my humble opinion, very decent. I wasn't blown away, but my expectations were met and I was intrigued by the story and entertained throughout the episode. I will definitely be tuning in for the next couple of episodes and ignore some of the bad reviews that I've been reading. The show is interesting and has potential to become a great show that will last for many seasons, which i hope it will.
My advice to you is, ignore the bad comments and reviews of the show and go take a look for yourself, you wont regret it!
