I really love Bones, but I feel like its gone down hill in the last couple seasons. I also love Dexter, but they kind of went nuts in the last season as well.
I feel like thats how a lot of shows go. I kinda liked how weird Dexter got, but other shows, like Lost, get weird towards the end (although I enjoyed seasons 4, and 5 of Lost). I never got into bones, but I should probably give it another try.
