To me, Highschool DxD is one of my all time favorite ecchi animes. Mainly because of how diverse the characters are and how interesting the plot is. The art is very good, but the animation (except the action scenes which are breathtaking) are usually not as focused. The story is pretty good but nothing special. Soundtrack-wise, this anime has a decent soundtrack, but gets repetitive most of the time and can be annoying after awhile. Characters in DxD are amazing and probably are the highest point of the anime in general. But the main reason you really watch Dxd is for a few reasons: tits, boobs, nipples, ass, boobs, and boobs.
Many of the elements of the anime are perfectly executed even if they are slightly "different" than any other ecchi's that you have probably seen before. Most of the plot is moved by sex, females, and sexual-orientated plot devices that while are different from many linear plot lines in other ecchi's, DxD does a good job of taking these elements and creating a plot around them.
Personally, this is something that I watch frequently as it is just a fun anime to watch. All the characters are interesting and good to love or hate. By the end, you will be ready to watch the 2nd and 3rd seasons as they are just as good.
