The Jedi being dicks and practically dragging Anakin to the darkside is the spiritual equivalent to all the horror film kids splitting up and going into a different dark corner filled with power tools.
It's unsatisfying in a fictional sense if stupid people come to a sticky end from acting stupidly (realistic as that may be).
It much more satisfying when everyone acts intelligently, does the right thing and still it goes wrong.
That way you have emotional investment in the characters. You care for them because if they can screw up what chance do you have in the real world?
The Jedi in the PT are so thick, so stupid, so random that it's a surprise that it took that long for a Sith Lord to do his thing.
If they are more crap at doing things than I am, I feel smug and superior and I shouldn't feel that way about telekinetic space ninja monks, I really shouldn't.
