I couldn't get into Psych through most of the first season because I had just finished Medium and Psych was a "similar show" recommendation. It was really nothing like Medium, so I struggled through kind of half watching it for most of the first season. I came to like it enough to be in the process of finishing it, but it's not on my top 20 list of shows I've ever watched.
My favorite BBC show of all time is Fawlty Towers. There was only one season of that, but I've seen it enough times that I can recite along with the episodes when I replay them, which I still do.
Fawlty Towers!!!!! I'm glad I'm not the only one!!! The Mentalist, I'm trying it out. Light humor, Mike and Molly!
