One of the most obvious problems with the PT is how they developed that anger--Lucas seemed to be under the mistaken impression that the best thing to base this on was Anakin's childish ambitions being stifled by Obi-Wan and the Jedi Council. Unfortunately, every scene where Lucas tried to get this across, Anakin came across as the most self-indulgent nancy in cinema history, and no actor could have elevated those emotions.
What's truly bizarre is that a
real basis for Anakin's "great anger" was sitting right there being raped to death by Space Bedouin on Tatooine, apparently for more than a Goddamn decade. There's the barest ghost of an implication that Anakin might have been constantly requesting funds, transport and diplomatic support in a bid to purchase his mom's freedom, and that these, for whatever reason, were constantly refused. It's certainly never made explicit, but maybe we can dream.
Yet even if this
is the case, it's still evidently not what he was actually pissed off about, because he never actually
mentions any anger toward the Jedi on this score in two whole films. It's an easy line to write: "Obi-Wan [Yoda, Windu, Jedi as a whole] let her die."
Likewise, and to a lesser degree, it is never raised to more than the level of apparently accidental subtext that Anakin is pissed because the Jedi don't let him bang Padme openly.
Those motivations are so much more compelling, and so much more sympathetic. An audience can comprehend blind rage at an organization that stood by uncaring while their mom died. An audience can understand rebelling against the homoerotic monastic strictures of a religious order that they've been trapped in since childhood.* These sources of "great anger" are never interwoven into Anakin's campaign against the Jedi, though. Palpatine never uses these to poison him against the Jedi, preferring vague assertions about immortality in the future instead of actively and accurately describing Jedi immorality, helping Anakin develop a coherent and principled opposition to the Jedi and attachment to the more liberal Sith.**
Nope, he's mainly pissed about not being immediately recognized as awesome, even though he isn't particularly, and not being promoted to Jedi Master as soon as his testicles dropped. Who could possibly care about that?
*A justification for Kid Anakin in The Phantom Menace? Horrifically, yes.
**Of course, this might open up some plot holes about the obviously wealthy and influential Palpatine not being able to help Anakin free Shmi on his own initiative. Minor chronological reshuffling could free him from this obligation.
