wow! I saw the movie opening weekend. I couldn't stand some of the people in it...but they all die anyway. I thought parts of it were good, but i'm a total dork. I thought it was cool that the guy who was in charge of the operation, Dr. Carmack was obviously named after John Carmack, the guy who designed the engine. The main guy in the movie (who wasn't the Rock) was also called John (as in Romero). So the guy building the engine and running the game was Dr. Carmack and in my opinion the guy playing and living the game was Romero. just like in real life.
Everything I know about computers I learned because of Doom. I do computers for a living, so I felt like I had to go see the movie. I really enjoyed the fight scene that was all shot in FPS but I never played Doom III, so I felt it was missing SOME of the old Doom elements.
