Orville just truly tipped over into full-on real Star Trek quality for me.
Grimes is fucking awesome. The actor himself is such a charismatic son-of-a-bitch it's unreal, and he's a genuinely talented actor. He really plays that like a legit ten year older version of the same character so it's striking when he reverts back to the younger one.
They could have ended that episode on the family photograph and I would have been happy to assume they went back, got the younger Malloy, and hit the reset button for the next episode. They could have easily set it up that way if they wanted.
Could have done without the lesbian crap even being mentioned, so there was zero 'muh CURRENT YEAR' shit for at least one episode. But it's character interaction and development at least - with a good logical reason for her and Isaac to be working together.
Good job with the time dilation shit, legit science crap that seemed well understood, but I thought the two-way trip was unnecessarily drawn out and undercut the drama a bit. Not too bad, but if you're in a starship what the big deal if you travel to a star twice as far away in one hit, then travel back with the field on as normal?
Great use of shit from previous episodes. Perfectly logical and believable. Cellphone, time device, holographic disguise, Isaac as human.
No future sandwich suddenly popping out of nowhere for the punchline/payoff? Sorbo DISAPPOINTED! Seems odd after they set it up, but maybe cut for seriousness of episode, or will literally 'pop up' in a future more comical episode.
Effects and visuals look great. Shows you what official Star Trek could have been, how there's still a demand for this kind of thing, and new directions you go, (also first time Orville felt truly original and not just a wholly derivative plot/theme).
