Fringe -> OMG so awesome, loved it i thought it was kick ass and has become my favorite T.V show currently airing. I really dig the characters and the whole parallel dimension thing. The series jumped the shark mid season, but then it rode the shark all the way across the Atlantic into the Bermudas triangle, and into complete awesomeness.
Lost -> Liked it, though it might have stepped into magic land a bit too much and is now more about some mythical stuff going on than anything, body switching and stuff, really?
The cliffhanger screamed of "We actually don't know were to go from here, so let's just cut it off right here and sit on it for 8 months".
Smallville -> At first i was like holy shit, this must have a bigger budget than Heroes, because i don't see people being punched through buildings in that one. Wow, this thing is more violent than Superman movies, lotta blood, awesome. And then, wtf, the guy jumps doomsday into this factory, the factory blows up and then it that's it. Superman lived, but i guess Doomsday died in the explosion??!! That was weird.
Dollhouse -> The little show that could, i disliked this series from the start but the last 3 or so episodes have been great i must admit. I thought the Season finale was pretty interesting, and definitely has me interested in a second season. I must say the whole "coming back from the dead" might be a bit too much to control though, pretty shitty story device.
