I just finished watching it. In my opinion it's quite a good show, perhaps even because it's very slow-paced in contrast to the other Marvel stuff. And the "super hero versus super villain" arc level almost takes a backseat to the dealing with the immense trauma of the tremendous abuse done by Kilgrave. Kudos to the cast. ?'s thought of Eccleston as Kilgrave made me chuckle as first, but actually that could have been brillant too. Not that Tennant was a bad choice.
The slow pace on the other hand also made for some weaker episodes, causing me to need about three weeks to watch 13 eps.
In the end, particularly after the final episode, I only have two things nagging me - and I realize both are caused by dramatic reasons.
1. Why don't they just shoot Kilgrave with a rifle once they decide to kill him? Given that they know his location numerous times, and these locations are on several occasions reasonably free of witnesses, that would be the prudent solution. Of course, there would be no drama in that.
2. They need 13 eps to think of the headphone approach?
Verdict: Liked, about 4/5. Will definitely watch the second season, too.
