A couple of years after the original, another director took up the Lawnmower Man concept. Actually, Mann picks up where Leonard left off.
The simple minded Jobe was turned into a genious by means of virtual reality. He keeps evolving and tries to take over the virtual world. In the first movie, an attempt is made to stop him.
In this second film, Jobe did not die, but was wounded. He is healed, again by means of virtual reality, by a commercial company that intends to launch an all encompassing virtual world and rule it. Jobe has other plans.
Mann uses concepts such as the internet in which all is connected, hacking, gaming, virtual reality.
I found the first film more interesting. 2 Is still somewhat amusing as well though.
