...some display to "show off" the hero ship which is what FC, Nemesis and Insurrection were guilty of.
Please elaborate: In what way? You make it sound as vacant as Mr. Universe flexing his muscles on the beach for the girls. It's kind of like saying an EMT (or some other first responder) is showing off by carrying an incapacitated person out of the fire. The latter two movies weren't great, so I won't defend that, but I am curious how you believe the ship essentially became an object of vanity. Your complaint is what some of us actually want.
