I love every bit of idea incorporated into the StarWars. The whole Jedi and Sith concept is fascinating. Spiritually powerful martial monks! Brilliant! But as with the filming of all great themes, there are limiting factors. It becomes very difficult to translate the scifi imagery into reality. The short duration of a movie also forces the director to omit various details. So the final outcome of a great story often cannot match up with the novel.
Take for example the Harry Potter films. The first two were great... they were thin books. But from the third book, the volume of the novel began to grow and the subsequent movies bagan to suck. I think the last three books should each be divided into two movies. Also the Dumbledore in the first movie had Charisma, they made a fatal mistake in changing him in the later films. The new Dumbledore is a stupid, rickety, bearded hag!
In
Harry Potter and the Sorcerer's Stone (2001)
Richard Harris successfully played the role of Albus Dumbledore. In my opinion, he is the perfect man for the job.
But in
Harry Potter and the Goblet of Fire (2005)
This most important character (Dumbledore) was given to Michael Gambon. Just look at the dumb cartoony figure! I dont hate Gambon, but he is not the right actor for this role.
