Every year I watch a handful of new shows. What I decide to watch depends on various things, such as creators, writers, directors, actors, storyline, etc. And of course, the all-important, what time is it on and does it conflict with something else I watch? That last isn't necessarily a barrier anymore though, since a great deal of new shows can be viewed later via Hulu or On Demand.
In the case of Terriers, all I really knew was that Donal Logue was in it, and Alan Sepinwall of What's Alan Watching really liked it. So I watched it and immediately liked it. The two leads have great chemistry and the story was okay. I can forgive A LOT if the characters are convincing. I'm not sure I would have made it through the first season of Supernatural if the two brothers weren't so awesome.
I've liked Donal Logue for a long time. He has a certain snarkiness and charm, and on Terriers he also gets to be a bit more dramatic than usual.
I don't think I'll rate these things cuz it seems a bit pointless, I'll just say I really liked it and if I had a DVR this would get a season pass.
