Well I watched the season three finale last night and at the end of the finale it said THE END. I think that is it for this show. All the stories were abruptly wrapped up in one hour and a major star of the show was killed off and buried. I can't find any trace of a renewal for this show for season 4 on the internet and I don't see it moving forward without a central character that has been featured since season one,so this must be the real end. So now that makes the last show I watched on Showtime and I can now delete it and stop watching Showtime ever again. The only premium service I regularly watch shows on still , is HBO and only because I get it for $10.00 a month.
