They almost all blow and the ones that have the potential to be good (Awake, Alcatraz, etc) are dying quick deaths because the ratings aren't there immediately. And why should they be? In the aftermath of the Lost series finale, why should people get their hopes up for a different kind of show if you believe it's going to let you down?
So what if JJ Abrams had said that he was doing Alcatraz and it was only going to have 48 episodes, 12 episodes a season for four seasons and that all the episodes would be shown in consecutive weeks (2-3 weeks between shows kills the non-CSI/L&O/NCIS type $#@!), would you have been more likely to stick with it or not?
By stating the number of episodes, he's not promising you a finale that you like, but he's giving you a definitive start and end date and then you can decide if you want to invest in the show whose story arc builds at its own pace. Didn't Fox show that this premise has a chance with "24" before they beat that $#@! into the ground?
Is it just written in stone that a network show has to have 22-24 episodes a season or can they allow for 1 or 2 shows in the manner I described above if only because they know not every show is going to make it?
Regardless, something must be done about network TV. All you have are reality TV shows, TV shows based off reality shows (Glee, Smash), Cop/Procedural shows and hospital shows. Very little character development, the sex is blah because either their is too much or too little of it, the suspense is manufactured and unrealistic and the shows have no real story arc beyond when the guy and girl character are going to $#@!. Now, I am the guy who started the "Grimm" topic, so it's obvious I don't need much to be entertained, but when I see a show like "Awake" about to die an unwarranted death, I get pissed because I know that NBC will replace it with another hour of reality tv or a L&O spinoff.
