Firstly, Jurassic Park has many more continuity errors than are featured in this video. The film has a ton. It’s discontinuity heaven.
However, I don’t think some of this video’s critiques are valid, namely the ones about Hammond having to be present for all the Mr. DNA intros, about the cars visiting the T-Rex paddock second, or the cars reversing their directions on the track. Any astute viewer should recognize that the tour these visitors are taking is not representative of the tour intended for actual future guests. The point of these people visiting the island is to “sign off” on the island, endorsing it for the sake of potential investors. The park is still unfinished. As Dr. Arnold notes, “Vehicle headlights are on and they’re not responding. Those shouldn’t be running off the car batteries. Item 151 on today’s glitch list. We have all the problems of a major theme park and a major zoo, and the computers aren’t even on their feet yet.” And as Muldoon later notes, “We need locking mechanisms on the vehicle doors!” They still have things to work on, things to finish. Even the visitor’s center is full of builders and painters working on the place. Think they’ll have that on the tour?
Also, as silly as the “Unix system” looks, it was a real system:
Of course, one must keep in mind that Jurassic Park’s computer systems and programs that ran the park were very flawed, as their development was apparently headed by Dennis Nedry, who, as far as we can tell, cared more about money than the integrity of his work. In fact, his computer programs were designed to let him sabotage Hammond, not keep everyone safe. Of course, though Nedry is sleazy, part of this is Hammond’s fault; his greedy ambition to be the first one to create something like his park blinded him to its many faults, not least of all its dependence on an apparently giant (two-million-lines-of-code is a lot) highly-non-modular highly-automated computer infrastructure to control its systems, an obvious recipe for disaster even if the lead programmer had the best of intentions and was simply naive. Which, of course, Nedry was not. After all, even Nedry knew better than to mess with the raptor fences!
