I was growing to despise Arrow over the course of the first season, but it started showing some real promise in the last few episodes and that has continued over to the second season. That last episode with Barry in the lab was truly awesome.
I have also enjoyed Veep a bunch as it's easily one of the funniest things on tv, and Sleepy Hollow is rather fun despite being incredibly shallow.
I wish the last season of Eastbound & Down was better. It had its moments (Especially his life story at the end.) but for the most part was really lacking compared to past seasons.
