We still have to watch the episodes from 4/28, 5/5 and possibly others (that I haven't catalogued yet), so I think we're only at the beginning of the creepy serial killer story. I know something funky has been going on with Langston, but maybe that's another story....
We started the spreadsheet when Fran got her hip replaced and we started to watch NCIS (in the 5th or 6th season). We were watching reruns on USA trying to catch up, plus trying to watch the new ones on NBC, after about a year we couldn't remember which episodes we had seen or not. We started to log the ones we had seen. Then Fran would watch TV shows when I was asleep and delete them by accident, so I started to keep track of them so I wouldn't miss episodes.
Because I used to design databases for a living and do market research analysis I couldn't help but use Excel to it's fullest for this need!
I think if you miss an episode of CSI, it's big. They always have something going on from show to show and when you miss one you wonder how so and so got pregnant, or why Delco and Callie aren't together any more, or what happened to Sarah and why she isn't with Grissom.
Sorry you don't get Modern Family regularly there in Australia, we just watched the one about "who will care for Lilly?" tonight. I just love the fact that they treat Cam and Mitchell as a "regular couple" that are just as crazy as the next one and not because they are gay, just because all people are weird. But they do have the right balance of exploiting gay culture, especially with the way they dress up Lilly and make her dress up as gay icons for photo ops!
