The series, unlike most series, just kept getting better as it went along. The last season was definitely the best, dealing with Lydia's problems being a single mom, Sammy and Ben at each other's throats constantly because of the lies and of course John Cooper's mounting emotional problems which doubled with the death of his partner. The gritty realism of this series has never been equaled. I just finished watching the entire series again, and it is just as good now as it was when it was first on television.
