I really like Demetri Martin, but this episode was quite underwelming.
It had it's moments, but somehow I expected more. Of course, he's used to doing more one-off jokes--perhaps he needed a bit of time to slip into the idea of each episode being themed instead of his usual random, grab-bag assortment.
That being said, I enjoyed his graphs (as I usually do) and his sketch on anger. There were a few other good bits, but if every episode is continuing in this direction than it's nothing to get excited about.
I hope it gets better.
Boring, boring, boring, boring, BORING!
