I said that and I certainly agree. I contemplated cancelling HBO and keeping Showtime because I don't watch much on HBO outside of "Real Time with Bill Maher".
I was already thinking if it would be in Showtime's best interest to air "Dexter" and "Homeland" at different points in the year, to spread out their fortune. Certainly the two do well together, but its food for thought, seeing as they've lost "Weeds" and their other original programming are not as big of draws for the channel.
