Mace looks great in his pilot's chair (sure it takes some surprise out of his turning up in time but we know he is on his way already anyway).
Perhaps it would work better if we saw the Jedi entering the system before the Arena battle began leaving the lead up free to follow with the anticipation building up in the background (keeping the audience thinking "Mace where are you?").
Nice to see poor Threepio with his dignity maintained too.
Kind of missing the Jengo fight but it never made sense (like Boba, I never understood why a bounty hunter would act as a body guard. his role in life is to find people for money).
It would be very difficult to do but it would be a much more dramatic entrance to have the Jedi land in the arena shoot up the intial threat of the destroyer droids on the way down and jump out of their fighters (like Anakin and Obi-Wan do in ROTS).
If the Jedi were that good at sneaking into a crowded arena I think there would have been more standing by the time the clones showed up.
A massive improvement none the less.
