I accidentally taped tonight's episode (The Truck) and watched it expecting fairly little. To my amazement (since I hated Meet the Parents and thought this was it's ugly stepchild), I really liked what I saw. The lead actor is incredibly charming and I found myself laughing out loud more than a few times. After 1 viewing, this show has made it on my coveted DVR list (I have a lot of shows I like and 2 roommates--it's hard to find room) and I'm now going back to watch the first 3 episodes and catch up.
I'm a big fan of sitcoms and I think Worst Week is a fantastic little 30 minute nugget of sitcom-ery.
