The simple truth of this discussion is there is no right answer. It comes down to the individual. What do you find to be a more involving experience? Most horror movies that try to build up a scary atmosphere and have lots of boo scares and jumps and monsters tend to turn into silly action romps or simply fail to engage me in the way the game did. Resident Evil the game is way more intense than the movie. Same goes for Doom. Also, games can be intense in a visceral sense, but hardly in an emotional or psychological sense, whereas a good deal of well made horror films have more to do with the characters portrayed than the number of scares they can elicit from the audience. In short, pick your own poison, but especially with the current trend in silly horror films, I find certain games to be far more frightening than many movies I've seen.
