Review of High School DxD
I think this is a good anime ( Akenos boobs aside) I think it has its own personal charm and i find it very entertaining to watch..although the perversion and border-line hentai stuff can get quite cringy at times I believe it can also be humorous sometimes...In my opinion this is a great entry point to any harem anime and if you enjoyed it i think you should definitely go ahead and watch the sequel seasons as at times they can be a lot better (and cringier)....I enjoy the art style of this anime (and no I don't think season 4 ruined it) and findthe action also entertaining although don't go into it expecting any masterpiece action anime fight scenes like in DBZ,Naruto,Mob psycho etc..its serviceable at best..
In conclusion if you are new to harem type anime than I think this is a really good place to start and see if you like it and if you already are a fan of this type of sh*t than you'll also enjoy what this anime has to offer,,I would give it a 7/10 if i were asked to rate it.
