I need a new series - out of town work for a few days.

As per title, I have work out of town and will have downtime at the hotel room. I would love another series to jump into. Right now I've watched The Unwanted Undead Adventurer, Goblin Slayer, Solo Leveling and Shield hero. I like the mature, dark setting. When it's mostly kids, I tend to be a annoyed.

Any suggestions would welcome :)
