I don't tend to review every show, on an episode per episode basis, because my expectations are not that every episode should be "AMAZING" but rather, that a show, as a whole, is entertaining and interesting.
The Class, to me, started out well and finished well. In between there was fun moments, and the bottom line is, that, it's not the most original show out there, but the cast/crew and the characters which this show is made of, are interesting and funny.
WHat will happen next? Who knows, but I'm looking forward to season 2 :)
