This may be my inner film snob talking, but I still find Avatar to be problematic. I accept that it is a big and bold science fiction film that is piece of technical mastery, but it needs more substance. It’s all well and good having the flashy visuals and the ludicrous action sequences, but if the plot and characters are flimsy then the film falls apart. It may be well directed in terms of visuals, but this is still one of the most ill disciplined pieces of work I’ve seen and one of the most overrated films of our time.

Visually is is stunning. And it is fun to watch. But I agree it isnt the most substantial film and definitely falls apart under scrutiny. I mean ‘Unobtainium’.. come on!
I prefer to use the title given by film critic: Smurfahontas
