To be true, I really liked this anime but like all other good anime's it has its bad points. According to my review pattern this is how Maid Sama is: (Try reading all the bolded out words to get a hint of the kind of anime it is)
The Story line was pretty weak and basic, the obvious girl-hates-guy-and-then-falls-in-love-with-him thing, but thats where Misaki's Secret comes in nothing much but its a break way indirect approach to their high school romance.
Most the charachters aren't very strong: Usui is shows to have a hard-core personality and he's probably the strongest charachter that bind everything together. Misaki has her place in the story becuase ofcourse the show couldn't go on without her but she leads a normal tired-off-too-much-work-but-willing-to-struggle kind of life. I think most the maids lead out the weak roles- they call have the same goals and aims.
The Animation truthfully was the thing that made me choose the anime. I always check out the animation before the story becuase I think the anime is what gives life to the story but exactly vice versa. The animation is good-and-good and the sound quality will pass as well. Even though Misaki could have had a louder yet softer tone.
