Retarded with a capitol 'R'

Just got back from Allen & Co. after watching the most disappointing movie of the year, Aeon Flux.  The biggest thing missing from this movie is a plot, which is kinda something you need in a movie. There was too much unexplainable events and too much predictable and unrealistic events. This movie was so terrible I don't even know how I am going to rate it, I started out with a D- but it slowly crept lower, and F just leaves a strange uneasiness to my stomach. So I am rating this movie an R-, cause quiet frankly it was worse than retarded.
