Will I go see it? Absolutely!
How can you not go see a movie that is as potentially as bad as this? Go, laugh, throw popcorn on the screen. Talk through-out it. Make snide comments, like
-If I were the DM this is what I would have done (explain in detail)
-If I were the director this is what I would have done (explain in more detail)
-You call that game balance???? On pg 118 of the rulebook...
-Calling out criticals or fumbles; (Ooooh, that's gotta hurt!)
-Whenever a pretty girl comes on screen, rehash the charisma vs comeliness debate.
Remember, talk really, really loud. If anyone asks you to shut up, hold up your Player's Handbook or DMG, and say "I've already read the books, so I know how this ends. Badly!"
