Season finale was like a normal standalone episode. I like the comparison between what happened with Kelly and the space Jesus theory on our Earth. When Kelly revealed that she wasn't a god, I would have preferred that she taught them compassion, kindness and justice instead.
Isaac spent 700 years on that planet but his personality and demeanor remained the same. I would have thought that he would have evolved also. He should probably know now all about human behavior, emotions and whatnot but I'll bet they'll just ignore this and they'll just show his growth onward in the ship.
Glad The Orville got renewed. This is a really entertaining throwback sci-fi show that is a nice reprieve from the dark, gritty, sci-fi series currently.
