300-Movie Evaluation

So Monday night i went to see the most epic movie of the year to date, 300. The entire plot and idea behind the movie was good as were the visual effects. My only problem with the movie was how the director decided to use slow motion as a major effect throughout the entire movie. There were countless moments in the movie when slow motion was not at all necessary, take one point in the movie for example when one of the guys got his head cut off, it immediately went into slow motion as the mans headless body fell to the ground. What was actually no more than about 20 seconds or so seemed like about 5 minutes as i watched the mans body fall. I guess the director found it necessary though since he used slow motion in almost EVERY fight scene and in many other parts of the movie. If i were a movie critic i would probably give this movie an 8.5 out of 10 because it was very visually appealing and generally speaking it was a good movie BUT i think the slow motion was a bit much at times. Any thoughts? If you've seen the movie let me know what you think.
