It also helps that the characters are likable, and while there is some minor conflict, they actual go about a civilized manner to resolve that. I guess that's boring to some, but if that's not the main story, then it's fine by me.
It just seems that shows like ST Discovery are built around interpersonal conflict on an extreme level. And with there being so few likable characters, it makes it hard to watch something like Discovery.
Even in DS9 (not my favorite Trek) the characters were all mostly likeable, and the conflict between protagonists were minimal. Even Odo's disdain for Quark was tempered with some degree of respect at times. And Quark seemed to have some admiration for Odo.
Discovery is all I hate you, I hate you, I hate you.... Even Stamet's and the Doctor's relationship was strife with conflict. Sheesh. I get that the Lorca was probably responsible for a lot of that, but he also seemed to prop up his crew in a lot of episodes. The main character is so full of self doubt, and has zero personality. The great lovable Tilly is even more pitiful and in no way would be on a starship. Stamets is an *******. Or at least he was. The doctor had no real role, so is dead, but will come back due to popular demand(?) despite having no role.... Saru is the only one that seems to have some degree of being interesting, but his character/ actor, lacks any real attraction that makes him possible to be a central long lasting character.
I just don't see all these issues in The Orville. You just have to give to Seth for understanding what Star Trek is about and having the ability to bring that to life.
Obviously I'm painting in broad strokes. People will disagree and prefer ST Discovery over The Orville, but I really think there is no real comparison. Orville wins, hands down.
