Continuity mistake: Worf's sash disappears when he is knocked over his console.
Suggested correction: I rewatched this scene several times. The sash remains on him throughout the crash.
Plot hole: When Picard is talking to Guinan inside the Nexus she tells him that he can leave and go anywhere anytime and Picard and Kirk go back to Veridian III just before the launch of the missile. Now why didn't Picard go back to when they first located Soran on the Armagosa observatory and detain him there? Or if he wanted to he could have gone back even further to Earth and saved his brother and nephew.
Suggested correction: This is a question, not a plot hole. Characters behaving differently than you would doesn't constitute a plot hole, and there's nothing contradicting the plot. The short answer is because of the Temporal Prime Directive. Yes, there have been several Star Trek episodes and movies dealing with time travel, but Picard knows it's best not to change the past too much. Plus, going back even further in time doesn't guarantee he'll be able to stop Soran.
Other mistake: When Worf tells Riker the Romulans were looking for Trilithium on the station, Riker acts as if he never heard of it before, and Worf explains that it is an experimental compound that the Romulans were working on. However, in the Next Generation episode, "Starship Mine", terrorists steal Trilithium resin from the warp engines to sell as a weapon, and Picard seems to know a great deal about it. (00:34:10)
Suggested correction: That entire Next Generation episode takes place on the Enterprise with only Picard and the terrorists. It was scheduled for maintenance and no one was supposed to be aboard. There was no reason then or now for Riker to ever hear of trilithium.
Continuity mistake: It's established in TNG that Geordi's VISOR can see the entire EM spectrum, which several episodes showed to be a chaotic, indecipherable, visual frenzy that Geordi admitted he had to train himself to be able to comprehend. In 'Generations', however, the hijacked feed from Geordi's VISOR is shown as perfectly normal vision that looks like what you'd see from any standard camera.
Suggested correction: Exactly, because that's what Soran did when he modified it. He adapted the VISOR so that it would transmit what Geordi was seeing in the visual spectrum without making him aware that the VISOR had been modified.
Audio problem: In Stellar Cartography, Data has to reposition his chair to work on another panel. To do so without getting up he places his hands on the panel to pull himself across to the other position. As he does, there is a sound of an electric motor moving him. But as the scene draws to a close and Data gets up, you can see the chair is a dressed up standard office desk chair, with casters, no motor, and no tracks for it to slide on.
Suggested correction: In Stellar Cartography, Data moves the entire console not just the chair. The sound came from the console, maybe it is magnetically locked in place, the sound coming from it unlocking and re-locking.
Other mistake: Historically, in the Star Trek universe, the doors to any room, including turbo lifts, opened automatically at a person's approach. The only time a turbo lift door didn't open was if there was no car there. This time Harriman touched a control at the right side of the turbo lift doors.
Suggested correction: Yes he did it to call the turbo lift. One is probably not there at all times.
