This show is so refreshing and good. First two seasons were terrific, the rest not so much. This happens with a lot of shows when they change the main cast - it just feels like a different show. They've written out characters and gave us unsatisfactory explanations (in some cases no explanation at all) for their absence. I've seen only a few episodes from series 3 and 4 so this review is focused on the first two series.
Simon and Susan were great characters. I could easily identify with them 'cause I work in school and I share some of Simon's attitudes towards students and my colleagues often come to me with their problems - that makes me feel overwhelmed at times, just like Susan.
The relationship between colleagues is warm and close. I like the fact that they could talk about a lot of topics, including silly conversations. They hang out after work, get involved in pranks and some of them are flatmates. The only character I didn't like from the beginning was Jenny, but eventually she warmed up to me. It's a shame that the main cast wasn't there 'till the end, but at least we got two excellent series with them. It's a fun watch, I guess that the young teachers will like it a lot.
