If I was the ruler of TV-land (spoilers)

I would change how they handle guest stars. For example, whenever there is a recognizable guest star on Law & Order you can guarantee he/she is going to be the murderer. The police will be investigating a crime and they go to a bar where a witness to the crime just happens to be Fonzie from Happy Days. Well you know right then that Arthur Fonzarelli is not just a witness to the crime as his role would be done in just one or maybe two scenes. The Fonz is going to end up being the killer so his role can cover the whole episode of investigation, arrest, and trial.

I also hate it when they announce the big guest star at the beginning of the show and/or in the description of the episode (in TV Guide or digital cable/satellite guide info)... especially when the star will only show up briefly at the end and they want him/her to have an impact with the audience. Last night on Heroes we learned in the opening credits and from the episode description that Star Trek's Mr Sulu (George Takei) was going to guest star as Hiro's father. No biggie if he had shown up in the first 10 minutes or so and had a storyline for the whole episode. However, the way it played out is that Hiro & Ando are running from some guys who eventually end up catching them and taking them to the "Big Boss" who, it is revealed in the last 5 seconds of the show, is Mr Sulu and he is Hiro's daddy. How much more impact would it have had with the audience if we hadn't seen it coming for the previous 60 minutes?

Remember the 1998 movie "Out Of Sight" with Geoge Clooney and Jennifer Lopez? It was pretty forgettable. However, in the last few minutes there is a scene where Samuel L Jackson plays an inmate. It's completely uncredited and comes totally out of the blue... and I'll never forget it because I didn't see it coming. There was also a scene with Michael Keaton that was uncredited and never promoted. It was awesome and memorable! THAT'S how you use a guest star to have the greatest impact with the audience.
