Entire season spoilers.

Spoiler:
I didn't particularly enjoy seasons 1 and 2, mainly because I'm not interested in a story where the main character doesn't encounter real obstacles or real conflict. I enjoyed many aspects of of those seasons, primarily the Russo and Stamper plots. This season, I felt was in many ways the best season because Underwood at least has formidable enemies for once, and seems to encounter genuine conflict. But there is a lot of crappy things about this season too. Not a lot actually happens, there's a lot of waiting for the other shoe to drop only to find that there was never a shoe to begin with.

My other issues with this show are the same as they ever were. An extreme lack of subtlety. The dialogue is always a character saying something nice and subtextual, then the show ruins that by explaining exactly what the character meant, either immediately or in the following scene. The editing sucks. Something will happen to a character (i.e. Claire flinching when Frank touches her shoulder for the photo), then a follow up scene that addresses that will be the very next scene. There should be interceding time to give the audience a chance to chew on shit before you spill the beans and spoon feed the correct interpretation to them.

This show is a third tier show at best, and I think I may be done with it after this season.
