The new movie Jurrasic World, which is still just a rehash again of Jurrasic Park with the same formula, thankfully corrects this. There are of course two kids, but the adults aren't idiots and the kids aren't smarter than them. The smartest thing the kids do is get an old jeep running by replacing the battery. I can believe a high school age kid can do that. But most of the rest of the movie they are running around by themselves when things are going well, but clinging to the adults when things go bad. In fact the adult man is not comic relief, he is allowed to act like an adult man and fix things.
Yes, I can see your point. But he also incorporates needless PC.., ergo his reimagining of the original ET where all the guns were replaced by walkie-talkies....
And to your point also was the SciFi movie about a train wreck, some teenagers and an alien something...
