Hinamatsuri finished its manga run and a second season could've wrapped up the entire story. I love the Yakuza dad taking care of his weird makeshift alien daughter. He should've stayed with the blonde girl that ended up homeless. It was a great mix of heartwarming, funny and with some action thrown in from time to time.
My Senpai is Annoying has a great cast of characters that could definitely carry the show for another season. Drunk girl and the tanned friend are best girls. Since it's a comedy, it has more than enough material and the manga does touch on more risque jokes that are funny but not really focused on in the anime.
Magical Girl Site ended with promise of revenge against one particular character and I did enjoy the dark atmosphere it has. The characters were interesting and it mixed drama with enough inner turmoil that despite being what some call "edgy," it made for an entertaining show that kept me watching the entire series.
School-Live! while the ending is fine, I'd love to see an OVA or movie that wraps up the story. I did like the mix from moe to horror in the show and the creator of the show is a horror movie nerd, so that's always a plus.
