TPM talks down to the viewer too much, it caters to kids under 10 in too many places, I find it unwatchable at times. But when you get to the meat of the story, it has great scenes smudged in there, and you could see if Lucas focused this movie away from the kiddies, it would be the best of the three.
Jar Jar is everything that is wrong with TPM. It is not just him and his annoyances, but Lucas actually went the route of slapstick humor in a SW movie and that drives me nuts when watching it. Jar Jar was put there just to make people laugh, or try to, and it comes off so bad it actually backfired.
Just take the scene when Anakin first meets Padme in the junkyard, that should be an iconic meeting that you would watch now as this haunting converstaion between the two tragic figures. And what do you get in the backround, Jar Jar doing Three Stooges schtick! He is fumbling and bumbling in the backround knocking everything over in the junkyard, and little Anakin goes, "Hit the nose!" UGGGGGH!
Then the big battle between Gungans/Droids is totally laughable now cause Jar Jar ends up doing comedy in the second half. The whole battle is utterly laughable now and contains no drama whatsoever, and is a symbol of how Lucas forgot that it is the characters and the drama that drive these movies, not the effects and action, they are just icing on the cake.
I guess all the PT movies are bad in their own way. ROTS is just a two hour mess that has to get from point A to point B. AOTC involves a huge subplot of who tried to kill Padme that is dropped in the overall arc of the PT, and makes parts of this movie irrelevant and illogical. TPM is just pure kiddie crap that doesn't hold up well after all these years. If I wanted a kiddie movie George, I would have went to a Rated G movie with my little nephews.
P.S. And I still hate when C-3PO says, "My parts are showing!" Come on George, don't demean 3PO!
