What have I done!?!
Edit: Okay, now I have:
Flaws in A New Hope: The title. I find the "Han Shoots First" argument interesting when people claim that it ruins his character, because if a single scene being altered can ruin a character, then the character wasn't particularly deep, which is mostly true about this film because they're archetypes. The ending isn't that great because it consists of all the cast standing around except for Luke, which is why Lucas ultimately chose to kill Obi-Wan off. I don't like the Jabba scene in the Special Edition because it adds nothing to the film and the visual effects don't work. Plus it has a gratuitous Fett fan service. Not really complaining but it's obvious why that's there.
I'd say A New Hope and The Empire Strikes Back are pretty much tied, maybe with Revenge of the Sith slightly behind, as my favorites. Honestly, I'd say all of them except Attack of the Clones I'm fairly fond of. Attack of the Clones is alright in terms of the art design and set pieces and score, but the pacing is abysmal and the dialogue is pretty bad, and those two things are what really separates The Empire Strikes Back as a good film from Attack of the Clones being an average at best film. I'm guessing Harrison Ford and Irvin Kershner saved TESB from having terrible romance dialogue, although some was filmed and thankfully cut.
My complaints about The Empire Strikes Back besides the general lack of a central story that drives the plot, which I think the prequels improved upon by shifting the focus to Anakin because Vader is the central character of the film and ties all the plotlines together, is mostly the replacement of Jason Wingreen's voice with Temuera Morrison (and that's entirely personal preference, though Wingreen's delivery is much more menacing). It has a few plot holes, namely the one I mentioned previously in which the plot is dependent upon Vader's plan which he formulates with information unavailable to him -- really, a lucky coincidence -- as well as the whole Millennium Falcon achieving interstellar travel with its hyperdrive damaged. It's also kind of odd that Obi-Wan waits three years to send Luke to Yoda, or that Han hasn't made any sort of effort to pay off Jabba the Hutt. Keep in mind I'm talking about the film on its own, not the EU attempts to resolve the plot holes.
Luke's plan to rescue Han Solo is fairly convoluted and if he succeeded in actual diplomacy would presumably have lost C-3PO and R2-D2 to Jabba, and his entire plan was contingent upon the foresight that Jabba would execute him at the Pit of Carkoon which would be the only way for Artoo to get him his lightsaber. The big flaw is that the movie is to some degree the dreaded "sequel that's a remake" in the sense that they need to destroy the Death Star again, except this time it's more complex, resolving the issue with the ending in the first film. Another plot hole is the fact that the shield generator is on the surface of Endor when starships that have shields usually (always) have them inside the ship itself. Curious decision. Granted, the film indicates that the shield generator itself was protected by its shield since Tydirium needed codes to bypass the shield to land on the moon.
I actually like Anakin's Force ghost being Hayden Christensen. Vader never looked like a healthy Sebastian Shaw. And no one complains that Luke's Force ghost in Legacy looks as young as he does, so I suspect it's a nostalgia thing. Most of the Special Edition alterations are benign. The Greedo shooting thing is simply stupid, but I don't think it does much to Han's character -- if he has a defining scene in the film, it's the control room of the hangar bay. The Jabba scene is annoying. The "Jedi Rocks" is tolerable but Lapti Nek was better. Don't like Temuera Morrison's delivery of Boba's lines, and simply like Wingreen better. I used to hate the changed dialogue for the Emperor scene in TESB, but now I'm indifferent, namely Vader's "How is that possible?" Originally thought it was stupid, now I think he's playing dumb so Lucas is playing up the betrayal angle. Vader's Death Fleet is off hunting Skywalker behind Palpatine's back while ostensibly hunting the Rebels!
