Haven't even heard of Billions, and The Wire is one of those shows that I missed at the time. By the time I heard about it being the greatest thing ever, there were already so many seasons in the can (ILTCIITCIWILTD) that it was an intimidating time commitment to get started. The Mrs. and I gave it a go for a few episodes, but it was pretty slow. I was ready for that, as word on the street is "give it time," but then I changed jobs and TV went pretty much out the window.
Some day I hope to get terminal cancer so I can sit in bed and catch up on all the rad shows I missed, but for now I'm sitting this one out.
