It's like you guys have never made the connection that great art can't save fucked up direction. Look at this!!!!
THIS SHIT IS BEAUTIFUL
And Phantom Menace is STILL widely regarded as an artistic triumph, at the very least, and it rightly was nominated and won many awards for its art direction, costumes, visual effects, and more. And some of the art that you posted that was accurately brought to the screen was some of the stuff that was praised as highlights of the film.
Yeah, execution is ultimately what matters most, and I actually think many of the prequels could've been salvaged in the hands of a better director.
But it's not just the art SKILL that we're interested in for the recent batch of concept art; it's the CONCEPTS. Some of those ideas, those themes, those character moments are absolutely arresting and evocative in a way the final film wasn't. Those story beats we're seeing - of the Oracle, of Supreme Leader Kylo Ren, of Chewbacca's interrogation - all have a gravity and imagination to them that was desperately needed.
