I had hoped the second season would herald something new, something exciting, something of interest.
I was wrong.
Pretty much the same criticism I've given every time, you extend jokes too long (the your fired joke for instance), put a lot of spotlight time on infuriating and boring characters (Yii and Gary respectively) and then try to real in a cheap laugh with something completely out of place and infantile (see butt sniffing in season 1 and Gary's shower in this one.
Also please use a new animation style, even a sloppy style for the mouths would help bring more life into the characters as then they can have more than 3 expressions.
