The first season was literally "What if 90210 analogues had their own show?" Without the parents/school setting its dull. Someone had the idea to turn it into practically a parody of how characters on soaps play sexual musical chairs for the second season and they struck gold. But IMO the show plateaued when Sidney died (or "died" if you count the 2009 revival). It wasn't fun anymore, it was fast becoming silly and dull. I stayed till the end but by that point it was a chore to watch.
