I started to watch this series totally on the basis that David Tennant was in it. Iw was a roller coaster ride to say the least. It is a great change of character for David from Doctor Who, but he is very believable as Killgrave. I found the rest of the cast very talented as well. This really is a dark, gritty, and violent series, but many shows are. My only dislike was that the plot did become predictable as the series progressed. I could probably watch anything with David Tennant in it as he is a truly wonderful actor. It does take an ensemble cast that meshes well to make a good story and overall this cast does just that. Overall, it was a good series.
