A lot of the dialogue is improv, so you can't separate it from the stars. And the plot is obviously hackneyed - no one, not even the people making the film would try to claim otherwise. Because the plot doesn't matter. Which is true for D&D adventures as well.But when I say 5+ years ago, I don't mean the structure in that broad sense (as you point out, that's far more ancient than 5 years, and I'm not a 20-something who thinks everything just happened just now lol), I mean the plot and dialogue. To me it seemed dated and clumsy, and barely being kept alive by the stars and action.
