All 3 of my favorite manga's have dissapointing (to me) anime's ;m;
Blue exorcist is my #1 favorite manga series. amazing art and just...The anime looked so boring and it had so much filler.
Bakuman is like smashed between 2 and 3, The manga has beautiful artwork and the anime once again was bland and put together badly
and kimi ni todoke in the manga was freaking beautiful! But the anime looked like doodoo and the only thing I liked about it was it's opening song.
oh well
they all had good opening songs tho!
