Indeed as the title suggest, technical achievement at it's finest, these blue aliens look as if they are real and believeable, at first I questioned it myself upon seeing the trailers, but sure enough Cameron doe not dissapoint! He found the balance of putting in real life shots and cgi together to make a believable looking alien and planet, none of that fake and unrealistic stuff that Lucas did in his last 3 star wars movies, can you say cgi overkill? To top it off his storytelling was so simple, to the point and very poignant. Cameron's the man, bow down to the master! Happy Holidays everyone! :)
