There were some strong stories, but overall it didn't wow me.
I was very impressed with Jibaro. The cinematography (if you can call it that) was amazing. I'm guessing it was all mo-cap, because I really don't see any animation artist managing that fluidity and type of motion.
Stories that I liked were The Very Pulse of the Machine and Swarm. Bad Traveling was ok. The Three Robots story started the whole thing very poorly though. A shame, since they are cool characters, but it was preachy and silly. Night of the Mini Dead was very funny.
But yeah, they haven't managed to get back to the heights of the first season.
