Person of Interest is pretty good. Of course such things are contrivances, like so much here...
Plus, it's on Thursdays, so if you've already settled down to watch "The Big Bang Theory", you just have to find 30 minutes of click, click, click until it comes on. I keep hoping for something decent in between, but no joy so far.
I was surprised at how fast "Rob" came and went, I mean, hey, that was pure comedy gold...
