The best of them all.

Rating: 9/10 (9 April 2014)

I gave it a 9, but it's an 8.5.
Now let me first tell you I was only introduced to the StarWars universe (or shall I say galaxy) in 2005, precisely when this episode was released, and that I did not watch the saga according to the release date, but rather according to the films numeration. Yes, quite unorthodox, but I was clueless back then. I can tell you I started my StarWars cinematic journey just because.
The Revenge of the Sith is the best episode of them all. The fact that I watched it before episodes IV, V and VI allows me to proudly say, brag, and write it, and feel the same towards the sequels as most feel about the prequels. A bit of a let-down.
Acting here is really good. Lucas achieves epicness by going so deep into the story, yet not losing it in redundant details. Everything makes sense and every frame adds something new. This is the one episode that contributes the most to the overall structure, greatness and complexity which is Skyriver, or simply 'The Galaxy'.
The reason none of the following three episodes is as good is because of the acting (it would be unfair to mention special effects). It lacks a dramatic approach whereas Revenge of the Sith doesn't. At certain points, you actually start to feel everything what is on the screen could be true. The notion of future and futuristic gets lost. That's the power of acting. Good acting.
Hayden Christensen's acting is much better in comparison to Attack of the Clones. His expressions are far more explicit and at the same time not as effusive. Ewan McGregor as Obi-Wan is something else. After watching him you realize he is The One for that roll. That's how I expected an adult Obi-Wan Kenobi to be. Chapeau to whoever was responsible for the casting.
The best expression I can come up with to describe this episode is 'emotion within action'. I for one am glad I watched the saga in this particular order, otherwise I would not be able to appreciate this fantastic adventurous scientific masterpiece as I did.
