Here's what I personally find wrong with the Geonosis lightsaber scenes

1. The fighting style (I loathe Nick Gillard's overchoreographed ballet-styled swordplay)

2. The (mostly) homogenous appearance of their uniforms

3. The lack of variety in the colours of their lightsabers (I fully expected to see more colours and more shades of colours in regard to the Jedi's lightsabers going into the movie, and was completely disappointed when everyone but Windu showed up with only the same standard shade of blue and green)
