Obi Wan says he was trained by Yoda in Empire Strikes back. We then learn this is not the case in the phantom menace, there is some Qui Gon guy who was never mentioned in the original trilogy but was his real master.

Obi Wan claims Anakin was a good friend who was slowly seduced by evil, nowhere shown in the prequels.

The so called great jedi purge is handled in a pathetic and anti climatic way in episode III, this is not Vader betraying the jedi and hunting them down.

Obi-wan treats Yoda as more of a master than Qui-gon (I get the impression that Obi-wan is with Qui-gon for field training before becoming a knight. Qui-gon is there and gone in a brief period while Yoda remains. Besides, with the creative history (with how the movies turned out) that Obi-wan had admitted to, why would this be any different.

Obi-wan and Anakin show a clear friendship and Anakin's fall is not abrupt, nearly every conversation with Palpatine is leading to his fall. Remember, Palpatine has had years of contact with Anakin that we don't see.

The Jedi Purge is not over when Episode III ends. Those were just the Jedi with clone troops. What about how Anakin went to the temple and slaughtered the Jedi there, even the young ones. How many other Jedi escaped the clones and need to be hunted down by Darth Vader (once the black armor goes on).
