Yep, first there was "Reefer Madness" (1936) telling of the pitfalls of smoking reefers. Now there is mazes and monsters madness. An undetectable force that you are powerless to resist.
Tom Hanks as usual fits comfortably in any role he plays. The theme may be a little dated, but it is still fun to watch and speculate "There but for fortune go I".
As you have guest the story is about a role-playing game that gets out of hand. Tom Hanks plays a person that might not be quite stable and the addition of this game feeds his fantasies. This leads to a mysterious disappearance. This is more of a physiological movie than a blood and guts type. Before people say what is real or not, different people will come to this movie from different backgrounds, and go away a little closer.
