Have to work in the morning, so here is the quick version:
I liked it!
I thought the resolution of Kara's S4 arc (with the music and the visions) worked really well. The juxtaposition of her hands on the piano with her hands on the FTL controls, and the music build-up, was gorgeous.
I loved the Opera House conclusion.
I teared up a million times at different character resolutions (when Anders drove into the sun, when Adama put his ring on Roslin's hand, when Gaius talked about knowing how to farm from his father, when Kara turned into an angel/pigeon and flew away, when Helo was still alive and running around with Athena and Hera, etc.). What can I say? I'm a total sap.
Sidenote: I've got a super-cracky icon idea that gobsmacked me while my piloty heart was breaking during that scene on Earth: if Kara is the pigeon that Lee can't hold on to because she's free and flying away blah blah blah, I want a Kara icon that says "I AM THE PIGEON, GOO GOO G'JOOB"
There were some things I was disappointed with, but I'll save those for a longer review. Mainly I wanted more for my girl, but I still think it was a good resolution to the show.
