I like to turn on comedy. I have Netflix, and a short attention span, so most of the time it's a 30-minute comedy TV show. Right now I'm watching Wilfred. (Really enjoying it.) But when I'm feeling really down - had a rough day, am sad, whatever - I like to turn on Saturday Night Live from the 1970s. It might take me a while but they're 1.5 hr long episodes that manage to distract me from my funk and get me chuckling and feeling like the world is all right in the end.
I'm going through Wilfred right now too! Absolutely loving it. I'm enjoying these darker sitcoms that have been coming out lately like Louie and Wilfred. I just saw an article on The Atlantic the other day (found it!) about darker protagonists in TV shows in general lately, like Mad Men in Breaking Bad. It's an interesting trend! It certainly makes for some enjoyable television, in my opinion.
