I have no interest in The Orville and frankly I am getting sick of people telling me every five minutes that I should watch it "because it's like TNG". I am quite happy to see a show that moves forward and changes. My debate is whether or not R rated changes add to the show. You haven't addressed that question beyond "It's a pay network series so they can". My question is, do they need to? What has it really added to these episodes?
They don't "need" to. But they can, so why not? Star Trek was always about being ground breaking TV (or so it though of as such). What ground did they break in the last 20 years? So if they want to do a little swearing, or show some T and A just to catch up, let them. I am guessing we haven't seen the last of T and A, or swearing, or something even more "shocking"
Oh and do go watch The Orville. It's pretty cool, and it IS like TNG. Watch it so that you atleast have some idea what others are talking about. Many people who didn't want to watch it, watched it, and like it.
