Wow, I was so out of the loop (spoilers)....
I watch the show on CBS.com every week, but I had no idea that tonight was the series finale. In fact, I forgot this was the last season (read up on it a LOONG time ago, but forgot about it)! Didn't even think twice that this episode was 45 min. long. Also didn't think twice how they recapped stuff going all the way back from the beginning, hitting upon the major stuff.
I had no expectations for how the series would end, so I think it was a fitting one, that I enjoyed. On the plus side, I get back half an hour each week again! :)
EDIT: Tie-in spoiler from Young Sheldon....
