I must say I enjoyed the film.
The whole was very good although it's too much information crammed in a small space. Mr Lucas should have changed his SW film length policy...
That's my big complaint.
Smaller complaints:
The Dooku fight was very VERY short
The Kashyyk battle was very short
The end was rushed
Tying up loose ends at the end happens really fast and feels rushed.
(see the pattern?

)
Yoda kinda gave up too soon when fighting Sidious although he probably thought he just couldn't defeat him in the end.
Darth Vader's Nooo! (I saw King Kong in that...).
Good stuff:
The lighsaber battles.
Ian McDiarmid<--------------STELLAR PERFORMANCE, BEST OF THE FILM + HIGHPOINT OF THE FILM
Hayden Christensen (very good as Darth Vader)
Ewan McGregor
SFX...Visuals to die for
Sound
More mature (well a little more mature...)
Palpatine's little talk about Darth Plaguis/Plagueis/Plagues whatever
James Earl Jones
Funniest scene in the film:
Yoda vs. the Red Guard
Order 66 was handled nicely also, time to die people!
And for the doubters, Obi-Wan totally won the fight, no excuses for Anakin. Outstrategised and defeated, all this talk (not here) about Obi-Wan just being luck annoys me to no end.
But then the Windu vs. Sidous fight...
Palpatine -
the sneaky little sob- making fake pleads for his life to get Anakin on his side but that doesn't take away from the fact that Mace wins in lightsaber combat and that Palpatine learns how exquisite Sith lightning feels...
Of course Force and lightsaber skill combined, Sidious is the master...
