A wise choice for your first rated R movie, @dnealy . Mine was Raising Arizona, which I went into blind, not knowing what the Coen brothers were capable of, nor who Nicholas Cage or Holly Hunter were. I have yet to be disappointed by any of their cinematic endeavors.
Editing to clarify I have not been disappointed by the Ethan and Joel Coen. I don’t go to any Michael Bay movies, and haven’t seen much of Holly Hunter’s work outside of the Coen movies.
