It's pretty good, well paced, with competent to even great acting.
But the script is so ridiculous. Despite high production values, the plot is like that of a kid's cartoon.
This film, uh, bombed badly, and I think I know why. A film with lead characters that are scientists/engineers/wunderkind is likely to appeal to that type of audience. And that's the exact audience that's not going to buy the implausibilities all over this film.
The worst to me is when he breaks into the lab. He visited the lab once and yet on a whim he is able to completely defeat the lab's security in a VERY elaborate operation.
However, it's still pretty charming. It doesn't take itself too seriously, it takes itself so EARNESTLY. It's kind of like Point Break in that respect- it takes a completely ridiculous high concept and treats it so respectfully, it comes out charming. It also manages to feel quite a lot like Wargames, as if it were set in the same universe, but without feeling at all like a ripoff. Basically, it feels like a well made sequel that manages to recapture most of the magic of the original., something very rare with actual sequels.
I was around back in the day, and I do recall this being advertised kind of as a comedy. I'm pretty sure the "does anyone have a Phillips screwdriver" gag being in a trailer. Apparently it was one of those pictures that the studio either didn't understand how to market, or decided to market it as something it wasn't.
There are some solid gags that fit in organically, like the screwdriver, uh, bit, but the, but it's certainly not remotely a comedy.
As a reviewer noted, Paul is a genius, yet is frequently stupid about things and not in consistent ways. This is annoying but I suspect that was done because if he were truly aware of these things, he would be quite evil. He's already pretty much a sociopath.
