The movie is good. As for the review, I think this one says something of interest:
The first two prequels met with widespread disappointment, though I was an enthusiastic proponent of both films. Only now, with the saga finally complete, do I fully appreciate in retrospect the extent to which the opportunity of the first two films was squandered. Yes, I admit it: I was wrong. The scales have fallen from my eyes. (I thought about writing new reviews of Episodes I and II, but on rereading them I find that I still mostly agree with what I wrote at the time, though I have more to say now, all critical. Instead of revising my reviews, therefore, I’ve supplemented them with short “final thoughts” sections [I, II] expressing my new difficulties.)
Unfortunately, the allegedly “narrow, dogmatic” Jedi orthodoxy never finds an equally articulate spokesman, not even in Obi-Wan or Yoda. Told by Anakin (in what may be a swipe at George W. Bush) that “If you’re not with me then you’re my enemy,” Obi-Wan retorts, “Only a Sith deals in absolutes.” (Really? The Jedi rejection of the dark side isn’t absolute?) And Yoda, his speech patterns sounding more convoluted and less sage-like than ever, has a final speech on the Jedi precept of detachment that goes well beyond Christian freedom from excessive attachment into Buddhist impassiveness. Attachment, Yoda teaches, is “a way to the dark side,” and our detachment and acceptance of death should be so complete that we shouldn’t even mourn the dead.
The problem with Yoda’s ethic of detachment is that it’s dead contrary to the unabashed humanism with which the whole story ends in Return of the Jedi, where human attachments — filial loyalty, paternal bonds — ultimately save the galaxy, destroy the Sith and the Empire, and redeem Anakin’ lost soul. Yoda and Obi-Wan consistently counsel Luke (and, in the prequels, Anakin) against the very bonds that finally lead to the triumph of good over evil.
In the end, alas, the Jedi do seem too “narrow” and “dogmatic,” not the great sages Lucas presumably wanted them to be. Perhaps the “prophecy of the one who will bring balance to the Force” was misinterpreted after all: Perhaps the prophecy was really fulfilled not by Anakin destroying the Sith order, but by Luke humanizing the Jedi ethic.

I said it before on EPII, but EPIII makes it clear, the Jedi indifference throws Anakin to the Dark Side as much as the Sith corruption.
You want to go free your mother from slavery? Tough luck, love leads to the dark side.
Oh, you are having nightmares about your mother and want to save her? Hey, dreams pass in time. Attachments are evil.
Hey, more dreams about someone you love? Dude, you must train yourself to not care about people. If something bad happens, don't do anything. You're a Jedi.
This is just plain horrible. No wonder the dark side looked so interesting to Anakin. Jedi answer to any potential suffering is not caring at all.
The incredible part is that they do the same thing with Luke on EPV and EPVI. Let Vader torture your friends. Kill your own father! Yoda give the same speech about killing someone you care about to Obi-Wan and Luke. Obi-Wan don’t even try to turn Anakin from the Dark side, he just laments and draw his lightsaber first.
Luke won because, I think, he choose not to follow the Jedi indifference but to act like a man. Caring turned Anakin and, in the end, was the undoing of the Emperor. The good that was still in Vader was that he cared about his son, not even being a Sith lord made him indifferent to that. Suffering because Luke was in pain is what set him free from the chains of the dark side. Compassion, not indifference, was the victory.
Jedi compassion is based on a vague love for everyone in general, not particular individuals. Of course that doesn’t work.
The reason for this, however, is deeper. George Lucas, apparently like Joseph Campbell, subscribes to a particular view about this subject that is voiced by Yoda. Suffering always leads to the dark side. It makes no difference if it's suffering from a moral evil, or because someone happened to someone you love. Suffering for being a bad or compassionate is the same. Of course that's bull, but hey, the movies were built on this premise. Luckily, for a reason or another, the Original Trilogy escaped from this fate.
EDIT: Yeah, I get it, Lucas is a Gasbag and utter a lot of nonsense. And he can't write a romantic scene, much less direct it. Even the action scenes were not as dramatic as they could be, but they were much superior the the avarege.
