As the title says, were there any shows that were better than what you were expecting them to be and you were pleasantly surprised? Shows that you hadn't heard good things from others, the manga didn't excite you etc. Which were those shows and why?
For me those were:
Tiger & Bunny: Wasn't expecting much from it but it was actually very good. Nice plot, good animation and characters.
Sacred Seven: I hadn't heard good things about it, so I was a bit hesitant to watch it but it was actually better than what I thought. Sure not anything amazing but the animation was good, the plot was ok and generally it was good to pass the time.
Baccano: Hadn't heard anything about it before watching it and a synopsis I read didn't exactly make expect a lot of things but I was happy I was wrong. Great animation and story,interesting characters and I have to say that Isaac and Miria are some of the funniest characters I have seen in a while.
There are more but those are the ones that come to mind right now.
P.S. I apologise if this has been done before, I searched and found nothing. If yes, feel free to lock it :)
