The best episode of the whole season, easily! I'm not going to lie when I say I thought this show was kind of a dud for the first season, but the second half of the second season really took off and landed squarely in "Awesome".
Although, if you haven't seen some of the previous episodes to catch a few glimpses, in this episode it is GLARINGLY OBVIOUS that the director/producers are fans of "The Matrix". Alright guys, we get it! You can stop with the quotes and the camera angles taken straight from that movie, seriously now.
All in all, great episode, and I really hope they bring it back for a third season; let's see what Chuck can really do!
