The revolving door of chief engineers got really irritating at this point. Logan was a prick and anytime he was onscreen or over the comm, he dragged the episode down. Thankfully they jettisoned him with the saucer, allowing the episode to improve greatly.
Schiavelli was a welcome guest star. I recognize the girl from Rambo 2.
But after having watched it, I can't help but wonder why Picard didn't ask the demonstration to end sooner. Also, why was the weapon in orbit still attacking the Enterprise after the demonstration was ended on the planet?
