Remember Your Roots, Jim. Please.

Sure sounds exciting and all, James Cameron finally directing another movie.
And "Avatar" is supposed to be a sci fi combat thing at that, like "Aliens" and "Terminator 1 & 2," for my money the best high tech action movies ever made.
Speaking of high tech, big talker Cameron promises all kinds of 3-D and digital animation breakthroughs in the new film.
And I've actually seen his little-known lead actor, Sam Worthington, in the terrific Australian coming-of-age drama "Somersault." He's good.
But whoa . . . There's an interspecies romance with some alien chick in the midst of all this? If her people - or whatever they are - don't approve, we may be looking at an outer space "Titanic" here.
Which may justify the film's already gruesome (and sure to grow) $200 million production budget. But if Cameron lets this one get as sappy as his last movie, some kind of artistic credibility will surely be lost.
It doesn't matter how many girls he made squeal, "Titanic" dealt in cliches and simplistic manipulation. Cameron's real creative genius comes out in his future myths, which may seem simple too - they're essentially chase-and-fight stories - but tend to have profund resonances like are found in only the most literate sci fi. And when he matches storytelling integrity to that singular visual dynamism of his, Cameron comes close to making the ultimate movie.
As opposed to the ultimate crowd-pleaser, which by its very definition would be some kind of compromised vision.
You've waited this long to get back in the saddle, Jim. Don't let anyone dissuade you (including yourself) from riding hard.
