I for one am very proud of J.C. Staff for sticking to the source material. While at times an episode could seem rigid and have poor flow from the first half to the next, seeing chapters from the manga coming to be animated brings a feeling of joy.
The art however leaves something to be desired. The change of color and designs of the characters from the first season and is not welcome. The backgrounds are fine but Nagi's hair looks like it was drawn with a piss yellow crayon, and Hina's and Ayumu's hair just screams QUALITY. But this is to be expected from a studio such as J.C. Staff, and it doesn't help that Japan's economy isn't so hot at the moment.
The sound enriches the episodes, and is the reason why this anime is worth watching if one already currently reads the manga. The seiyuu are all outstanding at their roles and the background music fits in perfectly with each scene.
The characters are extremely witty and endearing. The sheer amount of them and the developments between them is what makes Hayate so entertaining to watch.
