Maid Sama is what a lot of shoujo are. Cute, funny and entertaining. But it manages to do it better than a lot of other shoujo I've seen attempt it. (*cough* Fall In Love Like A Comic *cough*)
Characters: The characters are stereotyped as a lot of shoujo characters are. The main girl is tsundere and the main guy is... uh.... I don't know the term. Is there a term? Well, anyway. he's the strong and cool type. You know, the type that's good at everything. He cooks, he's athletic, he gets good grades... you know the drill. ANDDD.... He has an angsty past, too! SHOCKER! But not really. Anyway, despite this, they're still completely lovable. Misaki ( the girl) is fun to watch. She's interesting and you really don't know what she's going to do next. Usui (the guy) says some that I completely agreed with. I bet you're expecting me to tell you what it is word for word,. don't you? Not happening. because I can't remember it that well. But he said something along the lines of the reason he loved her (SPOILER ...but not really) was because she was so entertaining. You're never sure if she's going to smile or yell. And yes, a lot of tsundere are like this but I love the way Hiro Fujiwara pulls it off with Misaki.
Usui is just wonderful. He's just... great. He's hillarious and, even though compeltely unrealistic, a lot of fun. His comic face, I also would like to add, is AMAZING. I don't know why, but I just love it. It makes me laugh even to just look at it. He always seems very laid-back and also does the most random things at times that make you just go "...WAT." The way he compliments Misaki is perfect. They're a great comedic pair. I love watching the two of them together because the NEVER fail to make me laugh. Not to mention, go "Awwwe...." at.
So even though these characters aren't totally original, they're wonderful and I think anyone could love them. Also, the side characters are a lot of fun to watch, too. Especially Kanou and Yukimura.
Plot: Nope, the plot ain't that original either. It just carries the story and that's fine because that's all it meant to do.
Art: The art is average. It's not great, it's not bad. It does fit the story really well though, so I like it.
Overall: I personally love this manga. Definitely one of my favorites. It may not have overloads of emotional depth (which is what I preferr) but it's great anyway. I love a manga that can make me laugh. Honestly, I don't usually find a manga that can make me laugh but this one had me in tears. Not kidding.
Reccomnded for: Shoujo lovers. If you don't like shoujo in general, then this manga will not enthuse you. If you can even mildly enjoy shoujo though, you will probably like this manga. It might even make you think more fondly of shoujo. Also, if you like Special A you will also love this. Misaki and Usui's relationship is a lot like Hikari and Kei's.
