The Orville is a dramedy, not a documentary.
The bumbling professionals who don't deserve to be in their post is classic comedy ala Get Smart or The Pink Panther. Sure, if you overthink it, it gnaws away at suspension of disbelief, but it's a necessary contrivance in order to create situations like we had in the last two episodes, where characters are in way over their heads and they screw up left and right.
I know the show creates problems for itself by not having a clear identity. I get that critique. People are going to have unmet expectations. Ultimately you're either going to adjust to the wavelength of the show or you're not.
At least The Orville makes sure that not ALL of the crew are walking disasters, which helps balance things out.
What I like about LaMarr is he actually enjoys his job (aka my clip, Boom bitch!) Compare that to the poster children for anti-depressants in Discovery.
I like the fact that he is a walking unrestrained Id, basically a fratboy. It's not realistic and I...don't...care.
I've been guilty of it myself (since I'm very snobbish about entertainment in general) but I think there's an obsessive way of dissecting and critiquing entertainment that, taken to extremes, sort of sucks the joy out of it. It starts to feel like being a teacher grading term papers. If all you do is look or flaws, the only joy of watching a show will be to point them out on a forum like this. That's not to say that flaws, beyond a certain point, don't genuinely get in the way of enjoying a show, but I think some of the criticisms of The Orville do seem overexaggerated in relation to what it does right.
It's really simple. The Orville is probably not something that will go down in the annals of TV like Star Trek (or even MASH). However, what it has going for it are characters I give a crap about it, good music, some decent jokes that land well, and raises some socially relevant talking points, albeit with the subtlety of Fat Albert. And I don't feel like jumping off a bridge with the grimdark. That's pretty rare these days.
