Is there a reason you decided to take screenshots that don't show the critics' score? Is it because Discovery got 82% fresh while The Orville is 26% rotten?

And before you ask "Who cares about critics?", we all do as long as they agree with us, then their opinion is paraded around and slapped on DVD covers, it's only when they don't agree with us that "What do critics know?" or "It's for the audience!" comes into play.
And while I don't blindly trust critics (and have liked things most critics disliked and vice versa) they always tell me why they like or didn't like it in their reviews, most fans don't. Look it up on RT, most fan reviews are empty except for the score, very few actually make an effort.
About The Orville specifically: It's easy to see why most fans seem to like it while most critics do not. Critics dislike it because it's derivative of TNG, an old fashioned, cheesy sci-fi show where everything feels like it has been done before.

Like it as much as you want (I certainly like it for what it is) but don't pretend it's anything but a TNG clone, it's not like Seth MacFarlane ever hid the fact that he's a HUGE Star Trek nerd, he's basically one of us except that he's a powerful producer/writer/actor in Hollywood.
The Orville was meant to be a parody of TNG.
Nope, all the sci-fi tropes are played completely straight, the humor is clearly an afterthought and was probably demanded by Fox, but it is never directed at TNG, it's style, trappings etc., it's like MacFarlane wrote a love letter to TNG and then the post office said he can only send it if he puts a fart joke on the envelope.
