I applaud Lucas for trying to push cinematic technology but even with everything about them as-is, AotC and RotS would have been better movies if had stuck with actual film, real sets and props instead of going full-on, bluescreen only.
They’d still be just as bad. Real sets won’t fix a broken story. Real props won’t fix bad writing. Real film won’t fix bad performances.
If the films had a well plotted story, good writing and good performances the lousy effects would be forgivable. It doesn’t work the other way around.
