Season 5 - Creative High
Season 4 seemed to be the best, especially Episode 5 and 6 but I personally thought Season 5 was the best. Finally, the show lost that wet blanket Mary - wow was she becoming insufferable. Wretched actress, annoying voice, probably partially brain damaged - Mary (Nikki Cox) was terrible.
Sam and Delinda getting closer, introduction of great characters like A.J. and Piper, and better, funnier writing. Too bad the show didn't get keep the audience it started with. Tom Selleck's A.J. was great, Piper and Mike were adorable, and so were Danny and Delinda.
