^You delibrately left out the great
Piranha II: The Spawning 
.
Seriously though, much the same as
Titanic, Cameron's career is on the line (or at least his big budget career). This film has been so hyped that if Cameron doesn't at least show what the other side of the Uncanny Valley could look like, then there will be quite a few upset fans. And, if the story is too intelligent, then the average viewer might be turned off (generally speaking big and dumb sells far better than big and smart (just look at Spielberg's criminally underappreciated
A.I.)). In the end, I do have great hope for this feature, but, some part of me (my cynical side) is kind of expecting something similar to the abysmal Robert Zemeckis CGI films. So, while I want the best, I am prepared for the worst.
