I don't watch a ton of TV but one series grabbed my attention recently which was Mr. Robot. The pilot episode was phenomenal. It was well acted, well written, has a group of demented but interesting characters, and the computer hacking scenes were at least somewhat realistic instead of the shallow, slapdash way its done in other TV series.
Unfortunately the rest of the season devolved into "Fight Club - With Hackers!" and relying on shock factor to keep the audience's attention. I guess that was enough though to keep me interested as I watched every episode and I'm at least mildly anticipating season 2.
