I don't watch CSI JUST for GSR, but at the end of season 6, I was starting to worry I was, and considered stopping watching the show.
I guess I'm a rarity in that I don't WANT a ship to be the only reason I watch a show. I want there to be more to it. At the end of season six, I was really worried, but then there were a few really strong episodes (Bang Bang, Roshamama) that gave me more hope for season 7, and the big push to stay on another year (which I'm glad I did).
Yes, GSR becoming canon was HUGE and a big thing, but I don't WANT to watch the show just for GSR.
This past season was well-done in terms of balancing GSR and the rest of the story. The finale was beautifully done, and the GSR reveal was more perfect than anything I could have dreamed up. I just hope the handling of the season opener is done as gracefully.
CSI had a wonderful year this year in terms of stories and scripts, in my opinion. I thought it shined in a year when most series were falling flat on their faces. And, the GSR wasn't overplayed. It didn't dominate the show, but also managed to never leave our focus entirely. It was just so well done, and I can't wait to own Season 7. I will forever use it as an example of not how to do a relationship on a television proceedural PERFECTLY, but how to do it really, really well.
Sorry... Rambling... GSR does that to me.
