Important thing to consider with this is whether or not you like boobs, because you are going to be getting a shitload of them in this show... a friggin shitload. I dont think this is bad at all, a little fanserve (or alot as the case may be) never hurt anybody. There is so much fanservice that you dont even have to wait 3 minutes from the start to see a tit, or another 2 after that before there is a nude shower scene!
This show has a great story, it follows a guy with an innate special fighting ability and a devil woman who is saved him from death and is his primary love interest in the series. There is an interesting concept in the rating game that is used in the show-it is using people for chess pieces and duking it out.
This show also has alot of action, way more than I planned on in fact, the fights actually lasted more than 30 seconds! The fights were actually interesting and relevant to the story, which is almost never the case in a show like this.
It was also a very sweet story of romance obviously centered around the two people ive mentioned previously, and the way it ends should put a smile on anybody's face.
The art was fantastic, the characters were very well designed, the scenery was very good, and the fights were as previously mentioned very well done.
The characters were alot of fun.
Rias Gremory is a high ranking devil and the rest of the characters I talk about are her slaves, meaning that she saved them from death and now they are her underlings, not like whips and chains slaves. Rias has this one power where she heals any wound simply by sleeping with someone... in the nude... I suddenly want to break a few limbs. Issei is the protagonist of this show, he is a perv with a great power(funny how much these traits seem to intertwine) and he is in love with Rias. Akeno is Rias' right hand as it were, and theres not much to say about her other than that she is a lightning wielding sadist, which is awesome. Asia (not the continent) is an exorcist turned devil who has insane healing abilities, although personally I would rather get Rias' treatment. Kiba is a the very attractive male knight, and Koneko is the shows loli catgirl who also happens to be jacked. It is a very dynamic group of characters and they each bring their own unique attributes to the table.
Like I said before, i'd give this a 10 for sheer enjoyment alone, however every part of this was good enough that I feel that I felt any lower score wouldnt do it justice.
