You could do the ebola thing and then come in as saviors. Same result as number two with less damage to the planet and fewer witnesses.

THAT would be more dramatic, and a more plausable story. You could still have a big Tom Clancy like story dealing with the aftermath of that including shoot-outs and danger and all the immersive effects,too.

I guarantee that the aliens who survive who find out will want to shoot someone.

Cameron just took a cliche story because it's easier to pitch in Hollywood, and he's no Tom Clancy!:laugh:

There is already buzz about Avatar 2 in 2011. Look for it. :lol:  Haven't seen the first yet, but I would like to, regardless of the buzz.
