I've been rewatching Dollhouse on television (it is only just being aired in Australia) and it breaks my heart to know that it is cancelled after only two seasons.
Other contenders: Veronica Mars, Firefly, Arrested Development, Pushing Daisies.
Sue White is the funniest character. The quotes are not really funny if you've never watched the show. But oh well, I enjoy them.
(2.01) Would anybody like some haaaam?
(2.03) Do I look like a mug? Have I got a handle? Am I made of china? Am I kept in a cupboard or on a small wooden tree? Would you like to put your lips on my rim? You may answer that question, the rest were rhetorical.
When I started thinking about it, I actually haven't seen that many decent finales. Either, the show is cancelled or the show runs on too long and I stop watching. The only other finales I have seen are Lost and Buffy, both of which I feel unsure about.
It was hard for me to get to 30, so some of the shows are a bit of a stretch.
My real 13. and 30. are Cassie and Chris from Skins respectively. And really my 12. is Abed Nadir from Community. I also had a hard time finding 26. because out of my favourite shows, they all seemed to be either cancelled with an abrupt ending, dragged on too long and haven't watched the ending, or are still in production. But anyway, I had fun :)
Hell, yes, on the Buffy musical episode choice. I loved that! (Albeit not as much as my daughters...who still, at times, break out in song and reenact numbers from it!!!)
