Obi-Wan is described as being about thirty years old and wears all black.
The movie and the PT just got infinitively better right there

My take on all this is it's the same film and plot with just some key characters decisions that improve it vastly.
The character of Anakin floors me. I really like what has been done here given his age. Though the young actor to play such a role would be a hard task. I also find Shmi Warker very interesting.
Pros:
Kenobi's age, title and wisdom. Pretty much the Qui Gon role we see in TPM minus the years.
Anakin's maturity.
Binks is slightly more serious. Still comedic relief without the silliness.
Maul's additional presences and dialogue.
Reduced Jedi Council. No Yoda or only for the first movie would of been better.
Cons:
Kenobi only has Binks interact with for much of the first half of the movie. (In theory I prefer it this way but it could turn out worse than the alternative in practice.)
Palpatines rise isn't so clear.
I think with a director other than Lucas shooting this script (George handling the podrace and the like) we could have had a movie on par with ROTJ. It still has its flaws but I like it a lot better.
