Yesterday I watched episodes 2,3 and4. Not bad. I was entertained for the duration of each episode and that's really all that matters. I have a very low tolerance for boredom with TV so if I can sit through an hour long show and be interested enough to wait through a bunch of long commercial breaks them that meets my personal standard for what's good and what isn't.
It's obvious that every single episode is going to be a "treatment" of a plot or story that's been done before, So if you consider this to be a "ripoff" and it's going to bother you, you might as well not watch anymore, because that's what the show is all about.
I think that's why I'm actually interested in Orville. One of the reasons I'm lukewarm on the whole Star Trek franchise is that every bit of action or dialogue seems like it was written by a committee.
Seth makes space for the characters to act like ordinary people who, in real life, jibber jabber about stupid stuff and make sarcastic comments under their breath. We get to see characters that are peripheral to the scene react and add perspective, even though it would never be included in a "seruous" show because it doesn't advance the narrative. i appreciate that.
