I only recently started watching TVD, but i have managed to finish it in a week :O lol! bearing in mind i have just watched EVERY episode lol(so maybe watching them so close made it seem a bit repetitive) - my opinion was really mixed until season 3, i think that is when it really took off tbh, before that it was a constant snooze of decade dances and Stephan and Elena breaking up then getting back together lol, i couldn't really see past the "teen drama" and was really bored with alot of the supporting sub plots, They really pulled it off in the end though ! lol
today i found myself crying my eyes out at the season finale! (what a gimp lol)
Also for the record- DELENA all the way ! Stephan should of stayed a ripper lol.
