I think calling for “worst ideas” is just asking for arguments. But the second part sounds interesting.
I’d say most of Lucas’s PT sounds interesting in theory but falls apart because of the lack of character drama. I think if Lucas was better at directing characters we would have some solid Star Wars movies. A better directed Anakin could have been likable from the start, so we feel for him when he fails to gain Padme’s attention or feels constrained by Obi-Wan. Qui-Gon and Obi-Wan’s interactions with the Trade Federation could have been funny. And the one time they actually show great emotion - the High Ground scene - we would feel far more for these characters.
I also wonder if had Lucas written these as books, not screenplays, we would have liked, maybe even praised the storytelling.
