Enjoyable Addition to the MCU Being a huge fan of the Marvel Cinematic Universe (MCU), I put off "Agents of S.H.I.E.L.D" for ridiculously long time before checking it out. The show was already several episodes into Season 2 when I started watching on Blu-Ray. That said, I had reservations when I began watching. Luckily, I found myself enjoying the show, and finished the entire first season in one sitting.
The think that they did a good job casting, and the characters themselves are likable (at least the ones that are *meant* to be likable, that is). The plot is decent, though the twists are rarely surprising, and the tone fits the rest of the MCU. I was able to connect with show and became emotionally involved, which is one of the main things I look for in a series.
I do have two complaints with the series up to this point:
1. Plot holes. Tons of them. I won't list them, as I like to be spoiler-free, but there are a *lot* of them.
2. Nearly every single plot converges. You would think that Coulson's team would occasionally deal with something that doesn't directly feed into the overarching storyline... but, no.
As with most individual MCU pieces, there are always times where you can't help but wonder "Why didn't they call Iron Man / Bruce Banner / Black Widow?" I know that the actors are expensive, but it's hard not to notice.
Otherwise, "Agents" fits into the MCU fairly well and is fun to watch. I will admit that I enjoyed Season 1 more than I'm liking Season 2, but that is likely due to personal preference and not a reflection on the overall quality.
Definitely check the show out if you like Marvels' other productions. It really helps to flesh things out, and introduces concepts and ideas that I believe will be important to upcoming films (Civil War, for example). I think that the show should be accessible to people who aren't as familiar with the MCU, but that enjoy shows about people interacting with the paranormal such as "Torchwood," "Fringe," and "Warehouse 13."
