It looks depressing. Then again, the trouble-maker part of me thought about writing a "review" of the film. Or better yet, getting a bunch of us to write "reviews" of the film!

For example:
This 90 minute documentary reveals the amazing world of Dungeons & Dragons, a game where people play imaginary characters through role-playing in a fantasy world and are led by a game leader, or "Dungeon Master."
On a positive note, the film highlights the incredible creativity and intelligence of those who play this game since there are literally dozens of books, magazines, and other reference materials used. However, this reviewer found it interesting that the three spotlighted individuals were determined to merely be escaping from reality instead of using the game as a way of processing reality.
While it is true that many people escape from reality, studies show role-playing to be a healthy escape unlike drug-abuse or alcohol-abuse which are purely destructive. As with anything in life, you can take it too far. This reviewer wonders if the spotlighted individuals show were picked for their extremist behavior while demeaning the value of typical role-playing experiences.
Dungeons & Dragons (D&D) allows for improving social skills, math skills and problem-solving skills among its many other benefits. History appears to be repeating itself not unlike the Tom Hanks movie, "Mazes & Monsters," which gave viewers the impression the D&D led to an increased risk of suicide, something statics show is actually just the opposite. The documentary is an unfortunate representation of Dungeon & Dragons.
Truth is worth finding and life is too short to work for money.
