I realized this morning that Dexter is my first teleplay that I've written, and there have been many, that is NOT a network show, meaning I don't have to worry about commercial breaks.
When you write a spec teleplay for network television you must keep in mind "mini cliffhangers" to keep the viewer coming back after the commercial break. For instance on an episode of Law & Order the suspect is usually finally arrested after a lot of evidence has been gathered. "You have the right to remain silent..." commercial break...then you see the further development of the case.
For Dexter none of that matters as it's for cable television and runs straight through for 50 minutes or so (commercial television only allows for a 44 minute episode).
There must still be the usual plot points and story beats, but I find the freedom of writing a teleplay without the constraints of commercial break dictated mini cliffhangers refreshing.
