Patrick Dempsey is my favorite actor on Grey's Anatomy because Derek is my favorite male character not to mention that he is hot and sexy. I love Grey's Anatomy mainly because of Patrick as Derek and Ellen Pompeo as Meredith. Even when Patrick plays Derek as a jealous jerk, I still love him. Patrick has amazing chemistry with Ellen Pompeo. If and when Patrick does leave the show, he will still be my favorite actor on Grey's Anatomy and Derek will always be my favorite male character. Patrick Dempsey has does an amazing job as Derek over the past seven seasons. I cried when he got shot and Patrick played that scene well. I think it's one of my favorite scenes that Patrick has done as Derek over the years. Patrick Dempsey is and will always be my favorite actor on Grey's Anatomy just like Derek Shepherd is and will always be my favorite male character on Grey's Anatomy.
