I’ve watched Star Trek my whole life, and The Next Generation series almost non-stop since it first went on the air. Every week a new episode came out, we’d have the TV on during dinner to make sure we didn’t miss anything. It was a thing I remember fondly from my time living at home.
Probably wasn’t until a couple years ago that I noticed this “veteran” (Geordie LaForge makes this analysis of her abilities just a few minutes after this scene) of 24th Century Federation technology, Dr. Kila Marr, spent a good deal of time analyzing a cave by pointing her tricorder at herself.
I was really, honestly hoping that the new enhanced version (formatted to HD, remixed sound, etc) would’ve corrected this error.
