Can we vote for 'Everything after Season 3'? But off the top of my head, I voted for season 4 as the worst season. Not only did it begin one of the most contrived storylines the show's ever seen (Mala Noche), it devolved into a shadow of its former self while that particular storyline bled into season 5, and thus poisoned the rest of the series for me. Morbid, I know. But it Just. Won't. Die. I understand the need for a story arc, and it hasn't been the only one featured, but it's the one that ended up decreasing my enjoyment of the show with its incessant reoccurances. So while season 5 would probably warrant the vote more (because I did like some of the episodes in season 4--'Nailed', 'Urban Hellraisers', and 'Three-Way' come to mind), I remember having a particuarly negative feeling about season 4. It was sort of the end of something great, for me. On a more positive note, I feel as though the show has improved in some areas (definitely more recently) despite my qualms with that entire block that was seasons 4-7.
