IMO this is a good movie. One of the few Hollywood horror movies i can stand to watch. Some of the acting was pretty bad and the dialog could have been better but for the most part it was good. Definitely worth a watch if you have not seen it.

For those who think it is a rip off of doom, think again.
It took 5 years for him to sell the script to a production company and spent nearly 2 years in production before its 1997 release. placing it roughly 3 years before Doom.

Also the idea of Event Horizon is fairly well known and commonly theorized.
EH basically the idea that a black hole can transport you to another time, tear space, fold space and transport you to another area of the universe, another dimension, or for those who are religious.... send you to hell. All of which have been written about long before either doom or the movie. Given the mans body of work, even if it was written after the Doom video game was released i would still have to say that he took it from scientific theories and ideas.
