AH! Spring Anime! Nothing short of expecting what is good and what is not. Kamen no Maid Guy fell short of mine even if it is still at the middle of airing but I'm pushing through with my review for the heck of it. ^_^
Story:
Story?! What story? This series got the common "heiress/heir" plot with more ecchi moments at the start and starting to get lackluster nearing the end. Random moments are also imminent as the heroine tries to cope up to the cheesy but "fun" high school life as most anime series would use these days but with the addition of maid servants hired as "bodyguards" until the heroine would come of age to inherit the fortune much akin to Hanaukyo Maid Tai.
Art:
MADhouse animated this one and for me, the animation is pretty average to earlier works recently like Majin Tantei Nougami Neuro. No fancy artwork much used and pretty much consistent until now.
Sound:
Honestly, the OP/ED gave this one plus points for me. Kotoko did the OP and the song was upbeat and catchy while the ending is funny and heavy-metal influenced. Voice acting is average with the exception of Kogarashi. His voice is perfect for being the "Maid Guy" like being sinisterly evil but funny when caught in hilarious ecchi moments or jokes.
Character:
Boing! That much pretty sums it up for characters. Big-busted and not your above-average high school student, the main character (Naeka) kind of bores me with her attitude and traits. Same goes with other characters like her brother (NEET and likes to play eroges), a mysterious transfer student slash loli with her maids too. Particularly, only Kogarashi and Fubuki (the other maid) made good impressions for me.
Enjoyment:
Well, to be honest, I did enjoy this series at the start but it has begun to bore me approaching the end (slated for 12-episodes only as of this writing). One may enjoy the normal ecchi scenes and moments early on but it drags the storyline even more due to just an everyday episode in the life of the heroine.
Overall:
Give this anime a shot IF YOU ARE BORED or TO PAST TIME WITH but stay away from it if you are fed up with linear stories of ecchi/inheritance/maids/high school life type of anime series. The series looks promising if the story decides to take a turn for the good at this point in the middle but I'm keeping my hopes up for this series to end good...*crosses fingers*. :D
