When I got home, I watched DIRT! which was the season finale and likely the series finale, too. The show had filmed seven episodes when the writers' strike hit, and during the strike, FX decided to simply call it a day with seven episodes for the season. I have a feeling this will be all for the show.
Disappointing because I didn't feel very satisfied with any of the storylines except Lucy's. It's obvious that several other stories which were on-going would have been extended in additional episodes, so I was not very pleased with this serving as a wrap-up.
However, there has been no formal cancellation notice yet, so I'll keep my eyes open to read any news of note about the show's future.
