If you’re in the USA (because some cable channels are not available in Canada), 
I have discovered two new shows that the adults in my family are really enjoying: The Walking Dead on AMC and Terriers on FX. I am gripped by both of these shows. From the descriptions and the early buzz, I actually had given them a pass. But the positive comments from the twitter-sphere were too overwhelming to ignore. And, as usual, tweeters are right. These shows are awesome.
As I hinted above, these are cable shows for adults, so they are not for everyone. In fact, one of the frequent comments about The Walking Dead is that it does a masterful job of melding the gore and horror elements together with the character arcs and the plot development. But the gore is utterly over the top: the episode called “Guts” was aptly named on a number of levels.
Terriers is brilliant because it is funny and heartbreaking at the same time. Since I was turned off by every description of the show I read before I watched it (“losers as private investigators”), I can only advise you to try it out and see for yourself what all the buzz is about.
