To be fair as bad people think TPM is, it is still more watchable and entertaining than Titanic.
I'll take
Phantom Menace over James Cameron's cutesy romance writing and eye-rolling "muh rich people evil" nonsense any day of the week.
Also,
Menace got Duel of the Fates while
Titanic got Celine Dion. Contest fucking over.
Now hold on. Lucas was grubbing for dollars.
You'd be too if you were funding your own studio and every single one of its projects out of pocket. Remember that Lucas built Skywalker Ranch with the intention of being consistently self-funded, free of studio control, and operating as an alternative to Hollywood , where projects of both himself and other people could be realized in an independent sphere. It was something he and his other pals from film school like Spielberg and Coppola had always loftily talked about during their young, rebellious days: a permanent and fully-realized alternative to the Hollywood system.
Obviously, that didn't happen, and LucasFilm was already being outbid by other FX and film companies come the 2010's. Weta and Digital Domain were cleaning house with project after project, while LFL was lagging behind with only self-made internal projects like
Red Tails, which did dick for studio growth and profit. This is one of the reasons why Lucas was still pushing for animated projects like TCW and
Detours, AAA game and multimedia projects like
Force Unleashed and 1313, and ambitious TV projects like
Star Wars Underworld...so that the IP's exclusive to LFL could keep the studio afloat and realize its goal of becoming a full-fledged Hollywood alternative.
The only tempting alternative was to sell the studio to a company he could trust to allow it to function with independence and self-made creativity...and seeing the positive outcome of Pixar and Marvel's sale to Disney, to say nothing of Iger's relentless courting, Lucas opted to secure his company's future long after he passed away.
And we all know how that went.
The problem was that he was very excited about going all digital and new technical aspects of film making, and forgot the basics like dialogue.
Lucas has never been good at, or had any affinity for dialogue...by his own admission. He doesn't like to write scripts himself, or get involved with directing actors, primarily because he got his start as a documentary filmmaker. Rick Worley
touches on this in one of his videos, explaining the San Francisco film movement that Lucas aspired to be apart of...and why he puts far more emphasis on the technical part of film over the written or acted part of it.
Any time he had someone else take on writing and directing duties he didn't want, Lucas never hesitated to relinquish it to them. That's why come Episodes I and II, he raced to pass writing duties to Frank Darabont, Lawrence Kasdan, and Jonathan Hales, who all turned it down, forcing him to rely on his own scripting as a last resort.
He didn't get distracted by SFX or digital camerawork anymore than he did when he was writing the original Star Wars back in 1977. It's that this time he had no one to pass the duties onto, and already viewing dialogue and plotting as ancillary to the impact of "pure cinema" (again, there's that documentary filmmaker mindset again), he never felt the need to prioritize it over the presentation or visual messaging of the film.
If anything, I think that mindset is what led him astray on the PT, not excitement or autism over visuals. It's his unrelenting commitment to his way of filmmaking--which I imagine stems from some of his resentment of dealing with meddling studio executives who regularly squashed him on projects like
THX and
American Graffiti. That mindset likely is what led him to refuse to compromise on certain elements in regards to the PT, and what ultimately led to its greatest weaknesses.
But ultimately, the key difference between Lucas and a self-described auteur like Rian Johnson is that Lucas was actually willing to listen to criticism. Once ROTS' production came around, and the deafening criticism around Ep. I and II became to loud to ignore, he adhered to the requests of Rick McCallum, brought in acting coaches to beef up performances that Lucas wasn't interested in squeezing out himself, and reduced some of the planned set-pieces to isolate the story around Anakin's character more.
Listening to critics is precisely why
Revenge of the Sith became arguably the highlight of Lucas' career, and why every project Rian Johnson will work on after plugging his ears to TLJ's backlash will continue to get worse.
