Where to begin with whats wrong with this movie I love from 90s.

First off, i'd find the person who programmed the fans and have him override the 2 1/2 minute shut down feature.

When the lady was holding the electric hose in front of the prison bus, it was moving her around and acting like a snake. Last I checked, electricity didn't have this kind of power.

There wouldn't be timers and a terminal in where the fans were spinning. There would be no need for it.

There's a vacuum in the room below the fans.... yet there was no suction in the hole with the fans, makes perfect sense.

I love how in the movies, they act like politicians have no regard for life. In actuality, they wouldn't have opened any part of the tunnel in case someone was alive, because they wouldn't want their numbers to dip for the next election. So many 90s movies implore this
tactic.

After the explosion to seal off the leak, the liquid trailer starts to roll. Look at it, you see no weld marks on it where it was attached to the trailer and for some reason the stairs on it go all the way around it. Great prop hollywood!

In real life, all these people would have died from the explosion.
