Review of High School DxD

High School DxD Season 1 is surprisingly good, The animation is good, the ost is good, there is a decent story, which is pretty entertaining, and has no obvious issues, and unlike so many of these types, it is the focus of the series rather than the backdrop. All in all, season 1 is pretty good, it's entertaining, there is enough to keep you watching, there are hints of a rich lore and background to this, it has plenty to promise, and the ecchi isn't as obnoxious as it could be (that comes later) If you don't like Ecchi anime, avoid this, things will only get worse fromhere on out.
If you don't like harems, avoid this, why season 1 focuses on Rias, future seasons go all in on the harem aspect.
