Let's get over the really cool 3D stuff and astounding animation. Admitted--it's a visual treat. But 2 hours and 50 minutes of a paper thin plot, lousy dialogue, traditional white-man messiah saves (blue, this time) natives and gets the sexiest girl, good triumphs over the evil empire and I had a migraine. There is no sense of a deep mythology as there is in Lord of the Rings, to which it has been unfairly (to LOTR) compared. There is nothing innovative as far as plot lines at all. Go for the visuals, but don't expect much else.
Watching Julie and Julia is tantamount to seeing Betty Friedan's "The Feminine Mystique" tossed in a bonfire. I was insulted on a very deep level by the implications of the film for modern womanhood. The female characters in the film are either soulless career women, or are, hyperemotional melt-down prone casualties of an age which does not allow women to do what they really need to be doing--i.e. cooking meals for their, sometimes henpecked bread-winning and rational husbands. They are unfulfilled by their ventures into the world of men, and need to be brought back to a happier, post WWII era. They need to be encouraged by their husbands to take up "hobbies" that sometimes result in profitable ventures, as Julia Child's ventures did.
