I've smoked a good amount of weed in my day, played Dungeon's and Dragons, and hell, even LARPed a couple of times. In no way do I think this movie trailer accurately, or even humorously represents that. Even if the director and writers gather together and adventure through dimly-lit dungeons, I'm still not buying their "love" for the subject matter; nor do the ham-fisted jokes seem to ring true to my overly nerdy ears.
I suppose what I'm trying to say is this:
Someone please send me a gigantic bag of hash so that I may enjoy this movie.
