I think they ruined it when they killed Sarah, and had Linc hide it. Yeah, I know the actress left the show, but they should have given her a happily ever after. His love dead and betrayed by his brother, you've basically stripped Michael of all hope and left him with revenge. And that's not a Michael that interests me.
Next season spoiler:
Really, they had two seasons of brilliance, and I prefer at this point to pretend that season two ended five minutes earlier than what we saw on the screen. Just like I like to pretend that Nip/Tuck ended when Sean and Troy left Miami with happy endings for everyone, and try to forget all the L.A. shenanigans.Spoiler:
Yeah, I'll probably still be watching both next season.
