I finally went and saw Firewall Friday Night, 2-24-06. I had free tickets for a local AMC Theatres, and a local Loews theatre just converted to AMC. They still had the Loews signs up.
Anyway, it was pretty enjoyable, but it wasn't as techie as I expected. It mostly was towards the action side, with Harrison working to rescue his family. I didn't really see anything wrong with tech side, EXCEPT that Harrison took a picture of a computer screen readout with a Treo-style cellphone (Does a Treo take pictures? I can't afford one, so I don't know?), and then he goes to it later to recall the data, and apparently through a USB connection, he synchronizes the Treo's output onto a computer screen. But when he took the picture of the screen with the Treo, he captured a reflection of himself on the monitor in the picture captured by the Treo. When he recalls the picture later, the reflection is gone. It takes alot of assumptions; you have to assume that the accompanying software for the Treo, etc., and all the other little goodies is already installed.
All I know is, I can't boot up my Inspiron and immediately go into a browser to get online; I have to wait until Windows loads, and Macafee Virsuscan Enterprise loads, etc. Granted, Harrison was using his secretaies' laptop, and he probably went into Hibernation in the meantime, but I usually have to wait a little bit. Good ol' Hollywood, they always get something wrong.

One other scene: he pulls the car under the bridge and pulls out his former secretaries' laptop (he was forced to fire her by the bad guy; he gave her her job back later) which I assumed is Blackberry enabled and gets on the web. If that laptop was not a Blackberry, no WAY he could park under a bridge and find an access point from somewhere. I figure it HAD to be a Blackberry, but there was no mention of it. Of course, with what's going on now with RIM and NTP,they may not have gotten permission to use the name. Who knows?

Other than those two points, I didn't see anything wrong. No outrageously wrong IP address like Sandra in "The Net".
It was OK for a techie movie, but you can't really call it a techie movie, it's more like an action-suspense thriller. Harrison's gotten old, too.
I give it a 7 out of 10, but, don't throw away your VHS of Matthew and "WarGames".
