I hate to say it, but a lot of this stuff is just not that interesting to me. There are hints of the show that I once looked forward to eagerly, but for the most part I'm feeling a little bit... tired.
Cons:
So, there's a scale when it comes to characters coming back from the dead on TV shows. It can be done right, like in the case of Buffy, or can can be done lazily, as in the case with any character on The Vampire Diaries, or it can be done in a way that seems lazy but becomes the fabric of the show and part of the larger point, like, arguably, in Supernatural. Coulson's resurrection... I'm sorry, but I'm putting it firmly on the "lazy" side of things. His death at the end of Season Five was one of the most beautiful main character deaths I can remember seeing on a show. It was appropriate within the tone and the narrative, it had a good buildup, there was a sense of inevitability and yet up until the very end, you were watching still hoping for a miracle that would save the day after all.
And then he was back as a villain for a season, and now he's just... back. Okay, sure, he's an LMD, and I'm sure they'll do some exploring with that. But Clark Gregg just... being here, being all Coulson-ish, kind of erases the impact of that beautiful death two seasons back, doesn't it? The show isn't really getting a chance to explore a new dynamic, because the gang's all here.
