^^Imho, nothing beats character development. It makes for good tv watching, and appeals to the majority of viewers since the ships are quite split.

Btw, I think I would like GG to end at S3. I don't think it will happen though, I think there will be at least a season four since the CW loves GG. It's just that the writers should really focus on delivering a quality season to remember the show by. With one season to work with, they may not drag out the storylines too much and get repetitive.
