Well, I'm glad they gave LaMarr a bit of an overhaul. Aside from the awkward humor in the first few episodes, the biggest problem with the show was the bad stereotyping on this character. Going from one extreme to the other may have been overkill-- it's hard to believe that he would have kept up the charade when he was being sent to the brain-frying electric chair on "Majority Rules" world-- but at least it's an improvement. A nice touch was his comment about how easy it is to alienate people by being intelligent.
Interesting that Grayson has confirmed that they live in a moneyless society, and furthermore that the new currency is reputation. I wonder if they'll come back to this, because I don't think they've really thought through the implications of a post-scarcity society-- or if it's even possible to think through the implications of a post-scarcity society. Given the behavior of the idle rich and spoiled Millennials, et al, I don't think it would be a very nice place. If reputation is truly their society's currency, then bad behavior would be a bad investment and poverty would be ostracization-- which is not only not borne out by the behavior we've seen from the people in this show, but is pretty close to what we saw in "Majority Rules."
The 2D universe was very cool and I literally cheered when Mercer mentioned Flatland-- my Uncle Mike gave me his copy of that book when I was in grade school and it played a big part in stretching my little mind. I've got at least a couple of copies of it around here somewhere. The depiction of the Flatverse was fascinating, kind of combination of Flatland, an 80s video game, and an old-school circuit board. One thing this allegedly silly show does really well (most of the time) is embody that sense of wonder that is intrinsic to real SF. The view of the infinite plane of 2D space disappearing into the distance out the cafeteria's windows was amazing. I hope they revisit this concept at some point.
And in the world of ongoing plot threads, Grayson accidentally let it slip that she had put in a good word for Mercer with the Admiral-- he was understandably upset, but thought it through and it all came to a nice conclusion, once again demonstrating the maturity of the writing that underlies the inconsistent comedy. On the other hand, I was disappointed in the interactions between Finn and Yaphit-- I wondered if this episode might have been filmed before "Cupid's Dagger" and broadcast out of order, but apparently that is not the case. Hopefully they will at some point follow up on their "encounter."
