This show is definitely worth checking out and is a solid addition to the Marvel Universe. It definitely ties into the movies like Thor, Captain America, The Avengers, etc and its really interesting to see the side effects and aftermath of the events that happened in the movies happen on this show. I will say that it does start off slow and weak. The acting isn't the strongest, the dialogue is pretty bad and cheesy at times, and the plot is a bit slow and all over the place. However, once you reach to the Captain America episode which I believe is at Season 1 Episode 15 or so, the show definitely picks up by a lot. The action is great, there's a lot of drama, and its very tense. I haven't started season 2 yet, but from what I've heard, its definitely improved a lot over season 1 so I'm excited to see it. Don't write off this show from the initial impressions. Give it time, and I'm certain you will enjoy it.

Edit: I just changed my rating from a 9 to a 10. I have caught up and watched season 2 and it is by far leaps and bounds better than season 1. Unlike season 1, all the characters are finally getting fleshed out. The action is all fast and immediate unlike season 1 where things happened slowly. The plot is keeping me intrigued and I really can't wait for the next episode. I just watched the midseason finale and it was absolutely amazing. There was a huge reveal and a major tie-in to a future marvel movie. Quite possibly one of the biggest things to happen to the marvel universe, and I am truly excited to see where it goes.
