8.8/10 (Twilight Princess!)
By an extremely long way, my favourite prequel.
Good:
The battle between Obi-Wan and Darth Vader on Mustafar. My favourite battle of the prequels.
The three-way showdown between Anakin, Windu and Sidious.
Something important actually happened!
General Grievous
Ewan McGregor as Obi-Wan...again.
Obi-Wan and Grievous' battle.
Fantastic CGI and special effects. By far the best in the series.
Yoda fighting Palpatine in the Council Chamber.
Order 66 was shown very well.
It's actually reasonable to despise Anakin Skywalker now! (Do note that I don't despise the real Darth Vader)
They toned down the whole romance thing.
Very uplifting ending.
Bad
It's still not exactly A-class writing. Indeed, the writing leaves a lot to be desired.
Dying of a broken heart? Really?
Hayden Christensen actually managed to exceed himself by acting worse in this than in Attack of the Clones. Yoda, Obi-Wan, Grievous, Mace Windu and Darth Sidious made up for it...but, still.
