Probably gonna be a shytload more Chang with no Pierce, don't know how I feel about it. But either way I'm glad they're back for another year.
I have to say that overall season 4 was the weakest of the series, but I still enjoy the show and I like the characters and the cast continues to do a good job. I thought this would be the last season for sure, but NBC and its poor ratings continue to benefit the show.
With no Pierce and Jeff graduated, it will be interesting to see where they go for season 5.
The noncrazy Chang would be interesting like back in his señor Chang days , and I bet Jeff becomes a professor with his education degree
