This might be a good time to share with you a theory I have about this movie. You lucky people. When the movie came out, everyone knew that Arnold was playing the good guy this time. All the commercials went on about it. But I don't think you're supposed to know that in the context of the movie itself. The character, who looks just like the evil Terminator from the first movie, has shown up, crippled several bikers, and is now riding a motorcycle at night, with shades on, while "Bad to the Bone" plays. I submit to you that, at this point, we are intended to think him the bad guy. I'll have more on this as the plot develops. Assuming it does.
Back in the parking lot -- or possibly a different one -- a police car pulls up amid lightning and zappy sound effects. Apparently, there was an "electrical disturbance," which turns out to be code for, "Is it okay if I go off-duty while Naked Robert Patrick kills me and takes my form?" In hardly any time at all, Naked Robert is Officer Patrick in a police car, calling up John Connor's arrest record: trespassing, shoplifting, disturbing the peace, and vandalism. John lives with his legal guardians, one of whom is Vasquez from Aliens. She wants him to clean up his room, but he's working on his motorcycle. Incidentally. I know it's fun to find mistakes in movies and television shows. And I have no objection to it, in its place. However, someone has felt it necessary to complain about the fact that the bike has a four-stroke engine, but the sound effects are those of a two-stroke engine. Well, good job, dude. You found a moment of implausibility in this movie about time-traveling robots. You're a freakin' genius. John Connor listens to Guns 'n' Roses's "You Could Be Mine" (and if you weren't around in 1991, who are you to judge?), has a Public Enemy shirt, hangs out with a mulleted kid in a denim vest, and has hair hanging down in front of his face. Just the sort of kid who trespasses, shoplifts, disturbs peace, and vandalizes. Introducing young Edward Furlong, ladies and gentlemen. Try not to hold Pet Sematary II against him. John gets his foster mother to go away with the cunning stratagem of revving his motorcycle really loud, and now all I can think is, "That's a two-stroke engine sound." I don't even know what a two-stroke engine is. Foster Mom forces Foster Dad to go out and talk to John, but John roars away in a wash of two-stroke engine noises and Guns 'n' Roses. He's a rebel, that kid.
