so far to me most of it seems to revolve around gags... and the events revolve around lewd jokes.
The number of gags per episode has dropped off to just a handful. Some of the episodes spend most of their run time on fairly serious dramatic stories with just a joke or a one-liner here and there. Whether you find it funny or not, well, that's definitely a matter of YMMV.
Most of the show, is like this. You have one, maybe two one liners in the entire scene that are intended to be comedic. The rest is about the actual story/plot and is played entirely straight. "Dude, you're being a dick, shut up." Is the only straight "comedic" moment, and it does at least on some level match what the audience is feeling about the prosecutor.
Here's a scene you could literally pluck right out of TOS or TNG without any changes at all, except for maybe one sentence where the language is slightly colliqual and colorful. Hell, even the way Captain Mercer turns away at the end gives me Captain Kirk vibes.
Another example. Aside of the "Bang that chick on the kitchen sink." "I don't ever do it near the food." exchange the entire scene is played straight, and is related directly to the serious plot elements being developed.
Here's one where there's literally no comedy at all. Really. It's being played completely straight. Most of the episode is. The idea of the planet is treated as absurd by our heroes, but they don't take the dangers as anything but serious... And it's pretty close to classic Trek stories like A Piece of the Action and "First Contact." In terms of the way things play.
This scene, we have three fairly quick jokes, all fairly nice winks at tropes of Star Trek. Then we have a fairly serious, straight forward battle scene with a classic Trek style maneuver to out think the badguy, and it's followed up with a very nice bit of humor. Just a nice little fist bump.
I thought FIREFLY was funnier. THE ORVILLE is just not tickling my sense of humor, but I've never been a fan of MacFarlane's brand of humor.
Well i'll certainly agree with you that Firefly was a funnier, but i'm simply saying that's the kind of humor Orville is succeeding at the most. Back-and-forth between it's characters, and less the overt gags, which they have mostly dropped off entirely.
