I dont hate the PT films but there times when they seem to be brought down by bad scenes, and there are definiaty times when ive watched them and thought WTF! especially in the TPM at those funny looking podracers and announcers and especially Jar Jars antics in the Naboo battle, as for Clones I was in the cinema thinking oh my god!! at "I hate sand" the fireplace scenes,and the balcony scene in Sith and still think the love dialouge is pretty bad in Clones but dont cringe so much now as i am used to it if I watch it.
Adigitalman and Magnoliafan etc have shown in their edits what the films are like without what they consider "cringeworthy" scenes taken out and they do seem to work better and maybe are better films for this stuff taken out.
I think part of the problem is George cant seem write very good humor and seems to go for slapstick all the time, which maybe funny at first but can get tiresome and silly, and doesnt seem to write good romance dialouge and its like do people really say this!!.
