I'm calling it now. S2, E4 "Nothing Left on Earth Excepting Fishes" is the best episode we will get out of all 14 this season.
Including all the episodes from Season 1 as well, this was the first time in the whole series that we got through an entire episode with ZERO juvenile humor, ZERO profanity, and a great story that was both appropriate with dramatic elements, and also combined great visual effects in a space battle.
One thing in particular piqued my interest about this episode though. The Krill woman Teleya, who was posing as a human known as Janel "Tyler"... Well, in Star Trek Discovery, one might remember a certain Klingon who was masquerading as a human known as Ash "Tyler". Was this just coincidence? Or, just like with several other noted similarities during Season 1 of The Orville, was she intentionally named as such by Macfarlane as a way to say to CBS and Discovery, "See, this is what you did for your story, but we did it better"?
This should have been the Season 2 Premiere. I highly doubt any of the remaining 10 episodes will top this one, but I welcome Seth to prove me wrong.
