I wouldn’t really describe The Net as cheesy, if that is what you are looking for. The tech, while dated by the time the movie even came out, is more realistic than in most movies. It also had Sandy B starring in a strong role as a female hacker. The big problem was that the plot was needlessly complicated, and very hard to follow. It also lacked the charm that would have endeared it to a more targeted audience of computer geeks, which is actually what makes it less cheesy than a movie like Hackers.
Not a movie, and hackers weren’t always the focus of things, but the cheesiness of how powerful Questworld was in “Real Adventures of Johnny Quest”, from what I remember, makes me chuckle now. …that and how dated the CG looks now.
I’m a huge Matt Fewer fan (although I did not care for Lawnmower Man 2). He has been in a whole bunch of stuff dating back to the mid-80’s. I liked Max Headroom, but I really became a fan with Doctor Doctor. He has also done a lot of high-profile sci-fi TV series (he seems to show up in most of my favorites), along with voice work and a few small but excellent roles in major films.
On topic: Hackers is my favorite cheesy hacker movie.
