Same here. As I said, I still liked it, still found it entertaining overall, but it wasn't as strong as what we've seen already. And that's okay, too. Not every at-bat is going to be a home run.
TOS broke a lot of new ground, and at times the tone of that show varied a bit. I think there was more humor to it, intentional humor, than a lot of people remember. TNG had the benefit of learning from TOS, but was trying to update things for the 80's/90's as well as take it a step further, thus it too had to find its feet, and took a while to do so.
The Orville has the benefit of several series to study, and is mostly just trying to capture the same feel, with a few changes. Capturing the feel is working pretty well so far; nearly everything about it has an obvious TNG analogue. It's the "few changes" that they're still working out. How to balance the lighter tone with the serious themes. The balance just seemed off in this one, that's all.
Interesting that the weakest episode thus far IMO is also the only one not written by McFarlane.
