The actress who replaced Kelso is pathetic. No sense of comedy and clearly a self-indulged, pathetic actress not worthy of this show. Otherwise, it was an "OK" return to the series. This woman detracts from the spirit of the show and needs to GO. They need to find a way to bring Kelso back for the final season.
I liked the interaction between Sarah Chalke (Elliot) and Judy Reyes (Carla) and there were some real "come to Jesus" moments for the staff. Problem was, the episode was dominated by the overbearing replacement for Bob Kelso. BAD mistake, writers ... VERY bad mistake.
