My wife wants HBO. We currently have Time Warner including the basic HD channels. I can add just HBO for like $12 or I can add HBO plus one other premium for $17/month. I know Starz sucks so it would be Showtime or Cinemax. Which one is better and are either one worth an extra $5 per month. Also, I assume getting HBO would include their HD channel. Is this correct? EDIT: Ok, everyone seems to agree that Showtime and Starz are both better than Cinemax. So now the question is Showtime vs. Starz.
