This show is obviously inspired by Dungeons & Dragons, D&D boxed sets mixed with some AD&D, down to having monsters that can't be named, cause Beholders are copyrighted.

The main character's concept is what you get when your Ranger picks goblinoids as his favoured enemy. Every. Time. He's obsessed, he's ruthlessly tactical, he's the Punisher (Ennis's) in a fantasy setting.

I'm probably nostalgic about the good ole days of discovering the game and playing low-level chars, which may affect my judgment.
The story is simple, before domain-level play. Think red box.
On the other hand, it lacks complexity and an overall direction. Which is fitting: the chars go through the modules as you manage to get your hands on them.

Of note, this show attracted controversy for "featuring rape of females".
In short, yes. Although brief and not exactly explicit. Not for the younger crowd, but D&D isn't anyway.
The first episode opens with a level 1 party wipe. So, yeah, bloody and rapey. Because D&D is essentialist: goblins are evil, they commit evil deeds. Also, they start eating their victims _before_ they die.
But the pearl-clutching, eternally outraged crowd focused on 1 second of implied rape. What is wrong with them?
Well, they do choose the bear, and bears also eat their preys alive, so I don't know.

The animation is decent-to-good in the first series, and drops to sub-par in the second.
Still a fun watch, but not for kids. Or players of 5e.
