The trade federation were taking orders from Sidius in TPM, and even mentioned/showed his apprentice Darth Maul. Why were they in league with Sidius? What were they gaining by the exciting trade dispute/blockage? Why was Gunray arrested and then randomly appears again in the next movie?
Padme had no reason to tie it all the way back to a new character we haven't seen/heard. And then the Jedi just dismiss it because "it's not in his character". It was just lazy Lucas writing to show that an old Jedi is now a bad guy.
The First Order are remnants of the Empire that want to continue their ideals: fukk up the Jedi, embrace the dark side, kill Luke Skywalker, control the galaxy.
Can we mention the cantina ripoff in AOTC, that includes robot football, prostitutes, a dude selling cigarettes, and a callback to slicing off an arm, even though it makes no sense for the bounty hunter that can change it's face to attack a Jedi instead of just escaping? Oh, and Anakin Skywalker: Space Cop
Tried, and failed at every aspect.
