Sometimes James Cameron kicks ass, sometimes he misses. I'm one of the folks who thought the Director's Cut of THE ABYSS was amazing. I thought TITANIC had some harrowing moments, but the personal story was more melodramatic than I would have preferred. ALIENS is still one of the better sequels ever made, in my opinion. I liked the first TERMINATOR movie, but thought the Cameron-directed sequel was too precious and lacked the edginess of the first. I thought TRUE LIES was offensive to women and was surprised there wasn't more outrage expressed.
So who knows what Cameron's epic AVATAR will have to offer. Advance word is great, but so was the advance word on DISTRICT 9, which I thought was underwhelming and slight. Nonetheless, Cameron is an interesting director and he has spent many years bringing this new film to life. The teaser trailer looks like quite the effects extravaganza. Hopefully Cameron will bring a good story to it as well. We'll just have to wait and see.
In the meantime, here's that trailer:
