After nine amazing seasons, the "beloved" Simon Cowell leaves American Idol to pursue his other endeavors. Being the judge with the "mean-guy" reputation, Cowell's final crit was surprisingly positive. Regardless, contestants always showed much appreciation for the mean-but-honest judge and took his constructive criticism (for the most part) to heart.
As a viewer, I believe that Simon Cowell's presence will definitely be missed. Check out the tribute to Simon's 'American Idol' days in the video above, and see stills from the final episode in the gallery.
