“The Mind’s Eye” is a pretty straightforward episode. There’s not a big idea and or real character moment. Things happen in it, but they’re good things that drive a clear, well-developed plot.
It turns out that triangulation is really complicated. To the point that there’s also a thing called trilateration, which I don’t have time to read the wiki on. I haven’t really read up on them, but I’m willing to believe any number of data points Lieutenant Commander Data needs to find a signal source .
I feel like we skipped over how Geordi’s visor is a negative here. I think it’s fair game that the differences of the crew are sometimes drawbacks. Troi losing her telepathy in “The Loss” and Data being controlled in “Brothers” are both instances that spring to mind.
Derek’s episode pitch for a story where the senior staff is constantly implicated but not investigated for crimes is a lot like TOS’ “The Enemy Within.”
