For the most part, I try to focus on the content rather than the person. hal's delivery left something to be desired, but I agree with the basic premise that the saber fights in the PT are more acrobatic in part to appeal to a younger generation accustomed to heavily-choreographed dance-like fight sequences and "wire fu"-style acrobatics. I also agree with TheBoost that there is more to it than just that, and as is often done with Star Wars, you can point to enough in-universe reasons for the change to satisfy most fans.
