Which part of that 14-minute clip were you referring to? If it's the romance scenes, they're fairly corny, true, but I don't see what's so abhorrent about them. I guess it's all a matter of taste, I was just putting my opinion forward.
You can be briefly sucked in by the trappings of the genre, playing along rather like if you were watching an episode of CSI, but suddenly you realize the CSI episode is set on the Poseidon Adventure and as they carefully process the crime scene with the water up to their waists and rising (or in this case the utterly bizarre interactions of Padme and Anakin), you realize that this isn't CSI but some new form of absolute madness. Why?
The romance scenes in the prequels are like the "this is how to witness to people" scenes in evangelical movies; those heavily-scripted, responding to inept-argument perfectly for allowing further inept-argument to succeed as well until they break down and accept they are sinful and need saving. No such conversation has ever taken place in reality, though, because real people don't obey the script these come from, and no real person has ever been convinced by a stranger that they are sinful and need saving with mere verbal argumentation. (They'd exit the conversation long before you managed it even if you made progress.)
The result is inhuman, anti-human even. Half the scene is merely bad and scripted and inept. That's never fun, but it's pedestrian badness. The other half, however, responds to the first in a fashion that immediately renders the first's badness moot because it's moved to a whole other plane. Real people will not and can not respond in the fashion portrayed and thus you are instantly aware that you are watching a work of fiction and these are not real people. With your suspension of disbelief ****ed over, gg no re writer, not buying this as a story.
