Wow, i don't know many people who dislike it. I think the TNG-clone feeling is deliberate. I think like science fiction holds up a mirror to our world... they chose to hold up another mirror and simultaneously copy The Next Generation. There is the doctor, a robot/android... you quickly catch many similarities... but further along things start to get skewed, sometimes your expectations get fulfilled or ruined and they play with the stereotypes. I think it's kind of genius and often times gives it one or two additional layers of depth. Especially when they simultaneously discuss philosophical stuff and simultaneously play with TNG storytelling tropes. Like when they introduced people on the orville are vegan. and star trek still struggles with that today and people far in the future are super advanced, but randomly kill cows to eat them.

I also think the relationship between the android and the doctor has a certain cringy-ness to it. We currently see AI slowly becoming reality. It is very up to date to discuss people having relationships with machines. But they somehow do it in a weird and strange way. And too dramatic. But remember, there's also Wesley Crusher. And Captain Proton and some weird robots on Voyager's holodeck.

I don't know why you associate that "old" feeling with something negative. It reminds me of good times, watching star trek series as a kid. And to this date i like those sounds more than the atmospheric sounds of recent Star Trek. And I also like the light and bright spaceships more than the recent tv shows that all happen at night and have dark and dimly lit sets. like Picard.
