1. One Piece - great show, great story, great characters, this is the only show I've ever seen that has flawless filler episodes, there's a filler arc in the show, that you don't even know is a filler arc because it's so well written, I've literally never seen that before, phenomenal writing, also great art, nothing to complain about
2. Nodame Cantabile - I have a soft spot in my heart for classical music, so I gave this show a shot, and man was I shocked, the visuals, the story, nodame herself (<3) and good lord the music is flawless, a very good look into classical music, and this show does a great job in bringing out it's beauty, plus how could you not fall in love with Nodame and Shinichi?
3. Ano Hi Mita Hana no Namae wo Bokutachi wa Mada Shiranai - ...Where did this show come from? When the anime was announced, nobody was looking forward to it, plus it's an original work, so there was no manga to draw any hype from. Then the show aired...and wow, this show is the very definition of perfection, and Japan thinks so too, CD and blu ray sales are through the roof. The drama in this show is very well executed, all of the characters, except menma in my opinion, are all very enjoyable, and the ending made me cry...anime just doesn't do that anymore, plus ANJOU <333333
4. Kamisama No Memochou - It's like DC, but it's actually good! And I can say that with complete confidence after only 2 episodes, I look forward to see this show going places... even if it's from JC Staff >_>
5. Fairy Tail - Man am I in love with this show, there is a little more fanservice than I'm used to (mainly lucy) but I find the characters to be better than most shouhen characters, plus there's a flying cat voiced by Rie!
I'm probably the only one here who doesn't have DC on their list
