After all these years, this anime is still a masterpiece. What I like about it, is that it's basically inferno cop with a higher budget (but the biggest difference with the png parts is that their mouth moves, unlike inferno cop). The humor is pretty good for its time (and I think it still holds up till this day). Though one problem i have with it, is the female voice actors in the English dub, they sound like they are not even trying (amnesia is probably the best example, along with yamoto too). Ost is my favorite part, sad that most of it has not been uploaded yet. Finalepisode was probably one of the most hype things, kinda makes me wonder how was they going to do a season 2 with ninja slayer's new look (if they ever made one)...
Last thing I'll mention... "YEEART" "ABBAH" "AIIEE" "AAAUUUGHHH"
Overall, of course this anime is not for anyone, but if you like dumb silly good humor with a good plot with it all, then I recommend watching this anime.
