Pretty sure any point I make has already been made on this one. The bad acting ruined Eps 2 and 3...I mean, goddamn, why did they pick that guy for Anakin? The thought that Darth Vader, the most badass villain in the history of cinema in the eyes of so many fans, could possibly emerge from that mewling putz is beyond me.
Episode one had midichlorians. The comic sums up how I feel about that pretty well; they took a good idea and in one fell swoop ruined it through overexplanation. Way to go, Lucas. Way to go.
Final point...and this copies over to the newest Indiana Jones movie as well...
The movies relied far too much on CGI and special effects. Now, that's bloody rich coming from a star wars fan, considering the original trilogy had effects out the ass. But think about it this way. Watch A New Hope. Particularly, watch the death star battle. Every ship that blows up does such in a way that looks real. Now check out the prequels. The explosions, the ships, the entire scene...you can tell its CGI. Fantastic though it may look, it doesn't look REAL, which somewhat hurts the suspension of disbelief. Second point on this one, look at the lightsaber duels. Sure, watching Jedi act like a gaggle of freakin' ninjas going to town is cool, but the fights are remarkably sparse in anything resembling meaning. It's all show, no substance. Now look at when Luke and Vader duke it out at the end of Return of the Jedi. Every little bit of emotion the characters can portray, plus the running theme of the whole trilogy condenses into one fight, where Luke snaps and starts hammering the crap out of his old man. You'd think, say, when Qui-Gon died, Obi-wan would have some kind of similar reaction...nope. Not really.
And on a final, and personal note...Darth Vader is too badass to be reduced so. You spend two movies watching this angsty teenage queer pissing and moaning about his mommy fixation and his extraordinarily thin romance, which is about as far removed from Vader as it gets. Then, in the end, when he suits up for the first time, they presented him with the chance to redeem the pathetic, mewling whelp that was Anakin and make the ultimate villain. All they needed was a suitable display of rage, in some way shape or form. Did we get that? Nope. Instead, we get a man in the darth vader suit crying like an angsty teenager.
Lovely.
The movies were poorly written, the acting sucked (which isn't necessarily the actors' fault, considering some of the cast being people of fairly good quality), the substance was secondary to the appearance...
Screw those movies. I'm going back to the original trilogy...the ONLY trilogy, imo.
