If you haven't seen Red Letter Media's (a.k.a. Milwaukee-based filmmaker Mike Stoklasa's) take on the Star Wars prequels, they are really worth the lengthy video reviews.
Do note that his twisted sense of humor isn't for everyone, particular his "Buffalo Bob"-style narration and the "Mr. Plinkett" scenes in these reviews can be distracting. (My take is he does this in the reviews to say that it's even obvious to someone psychotic that these movies are terrible ... or he might just enjoy playing a psycho.)
Regardless, he does have some salient points about filmmaking, particularly on establishing a protagonist the audience can identify with and actually having a story arc in your movie. Stoklasa also does a great job at pointing out the pitfalls of completely digital filmmaking and a (seemingly) lack of true collaboration between Lucas and his staff in the making of these prequels.
If you haven't seen it yet I'd start from the beginning with his review of The Phantom Menace, but if you've already seen those, Red Letter Media's take on Attack of The Clones is now out.
