IMO that entire opening sequence (up until our victorious heroes land on the Senate platform) drags like an AT-AT in cement. The key part is the Dooku saber duel, and the rest is just filler that frankly bores the hell out of me.
I would have
--cut the buzzdroid sequence to get them onto the flagship much faster,
--cut every shred of battledroid dialogue (man, that was stupid)
--and all the elevator hijinks
--and the R2 fighting sequence (it's amusing but pretty irrelevant and silly),
--added back in the Shaak Ti/dunk tank series for the aforementioned reasons
--and cut the protracted crashing sequence to a much shorter length.
This would get us into the main story faster and free up 10-15 minutes for the Birth of the Rebellion scenes and so forth.
Thoughts? Am I alone in thinking the present cut is the boring-est opening 20 minutes in any SW film?
