Yep, some good points in here. If you skip days writing creatively, you should spend some time that day on analysis of plot structure in successful vs. unsuccessful shows and movies. Try to quantify exactly WHY one show just seems to suck by writing a page of detailed explanations. Then counterpoint with a similar treatise on why another show is great. It still seems like a lot of shows slip through the simple great/terrible filter of: Do I care about the characters? Is it engaging? Does the plot draw me along with it? Am I satisfied at the end? ... That kind of stuff.
