The series discovers a new life of Greg Davies as Dan, who has character flaws. In this series, Dan has a lot of obstacles and still has a new chance, as he has an unwanted teaching job and dysfunctional friends.
The supporting cast were caricatures rather than characters, the dialogue didn't convince, the script's swearing seemed gratuitous and jarringly jaunty music played to signal that this was all a bit "madcap" and "wacky."
Some slapstick scenes that are so preposterous as to be surreal... It's touches such as these -- and Davies's utterly silly but joyous classroom scenes -- that could have you warming to both Davies and the series.
