Do You Watch Premium Channels For the Movies or the Series?

There was news this week that Viacom, which owns Showtime (as well as CBS, the CW, Paramount Pictures, and approximately a billion other things), will be launching a new pay-cable channel in 2009. Unlike Showtime and HBO, which carry both movies and TV series, this new channel will have movies only.

I'm a relatively new subscriber to premium channels, but it was the TV series, not the movies, that convinced me I needed HBO and Showtime. What about you? If you have premium channels, do you watch them more for the TV shows or the movies?
