Comparing different genres of movies to each other and tauting it as the best and what they represent is not the correct thing to do.
There is no movie that has ever been shot like AVATAR in the way it was done - the cinematography is simply excellent. It is visually superior to anything we have seen this year, imo at least.
And No, the story and plot is not great, or even original in places, but it also is not bad or terrible or old.
The scientific parts of the movie - actual planet (location, existence) and its moons, the six-legged animal species + flora, atmosphere of the planet, etc.) is actually, factually very close to reality and quite plausible, much better than other (even non-sci-fi, fantasy, action-adventure) movies that were put out in 2009.
There is a reason there are different categories for movies at the Golden Globes and the Oscars - each categories have great movies in their own right.
Having broken through the $1B worldwide mark (in 3 weeks!), there is no denying the absolute pulling power and intrigue AVATAR demands , either via word-of-mouth and /or marketing... I mean they did spend like $250 million on the marketing alone
Only Titanic is in its path, and the big boat can possibly be sunk with its $1.8B revenue total.
And as for memorable quotes, what about these...
Col. Quaritch: You are not in Kansas anymore. You are on Pandora, ladies and gentleman.
Selfridge: [from trailer] This is why we're here, because this little gray rock sells for twenty million a kilo.
Jake Sully: [from trailer] They've sent us a message... that they can take whatever they want. Well we will send them a message. That this... this is our land!
Neytiri: [from trailer] You should not be here.
[from trailer]
[to Jake, before he becomes an Avatar]
Dr. Grace Augustine: Just relax and let your mind go blank. That shouldn't be too hard for you.
Col. Quaritch: Gives me the goosebumps!
"I See you" is one of the less memorable quotes imo.
Also, don't tell me any of you forgot, or missed, the name of the ore they are after on Pandora (which should scientifically rather be classified as a mineral) - Unobtainium - an old sci-fi insider-joke.
I could barely believe 2.5hrs flew by the way it did.
