House of Cards. There was so much I liked about it -- it was pretty intense. At first I hated it, but once I got into it I found it very compelling. Creepy and fascinating. The relationship between Frank and Claire Underwood was particularly interesting to me. Their cold quest for power and their ruthless competence.
As much as I liked it, often it was tedious. The plot sometimes was hard to keep up with, and at times it felt repetitive. Still, I can't wait for Season 5!
