Yeah, so it looks like The Judge Returns will definitely take on a more unhinged approach to the main character's personality, just like Bad and Crazy does. So if you're into all-over-the-place, extreme behaviours MCs, these two dramas offer them.

More similarities - a legal setting (judge vs. prosecutor), some trauma, a good support team.

Going only on the first ep of Glory - similar story of multiple female main characters, smart ML, conspiracy in Ancient China, enemies-to-lovers trope.

Loosely related through the industry the women are in - tea plantation vs. teahouse.

Good production values in both, great casts.

Two world/time-explorers with their own motives, one experienced, the other new to it. Male-lead drama. Maybe hints of at least strong bromance in The Company (censored danmei in The Spirealm).

Good (unexpectedly good) production values. Pretty good ED song, nice OP, too.

These are basically the best two BL kdramas to come in the past few years. There's pretty good acting, vulnerable MC, hurt and healing, good music, decent time to develop (they could always use more, but at least the eps are long enough). And people actually have great chemistry and are not afraid to get close and touch.

Both are highly recommended.

Old cases that seemed solved turn out to be cold cases. Same eerie small-town atmosphere, where everybody knows everybody else's business but at the same time murders were committed and people were blamed when they were not guilty, based on how the town perceives them.

Also - personal hurt and obsession / drive to solve the murders for the leads. Nice plot pacing (though slow).

Police stories featuring life at its most frustrating part. Both present very long cold cases, with slowly addictive characters, driven by obsession and stubborness. The mysteries aren't revealed all at once, it takes a very long time in both dramas to find out whodunnit. Kind of a similar atmosphere of weighty expectation for the leads to finally solve it and be done with it in order to live the rest of their lives freely.

... And lots of missed chances (that's the frustrating part).

10 Things is a lot more romantic-driven than Chosen Home, but still, it's about an older gay man who is too lonely for his own good until he finds love.

I've no idea if Chosen Home will go there (and if it does, it definitely won't get there by a too-romantic way), but it's interesting to see older people's romances, as slow and mellow as they might be.

Forced cohabitation leading to close relationships in both dramas. Also, again, found family trope.

A bit of a loneliness trope healed by doing stuff for your fellow man (or woman) in both of them, too.

Both are slice-of-life stories, dealing with everyday situations that also involve a bit of a strange turn once in a while.

Umi no Hajimari and Chosen Home also deal with found family - one blood-related, the other formed out of strangers, but still basically found-family.

Both seem to be very warm (Chosen Home has just started, but it does give off that feeling) and healing.

Both dramas are inspired by European original stories (one an original drama, the other a novel). They also share a support actress and the director. Sadly, it looks like the technical team isn't the same in Mantis as in Black Out, because it definitely shows. So far (ep 1), Black Out is the better drama. But if you want an European-feeling in your police kdrama, this could also be it.

Both dramas involve detectives taking a practical approach to solving crimes (as in, staging a crime scene, taking in all clues, etc).

Both also seem to be more male-centric with less romance, which IMHO is good for detective stories. Both also involve (some) humour.

Both dramas involve a lot of action and some vigilante justice. There are knives and good action scenes involving them, and also a lot of mobsters doing their thing.

Pretty interesting MCs in both stories.
