I have no problem with big-ticket blockbusters if they are done well. Unfortunately for me, being done well includes a story or direction that I can be drawn into. This includes interesting characters and a plot that hasn't been rehashed twenty times with a different skin. Atmospheric direction/sets/special effects immerse you in the story. To me, Bladerunner, Alien are great examples. While Avatar had the special effects thing covered, it was woefully lacking in anything else original or even interesting to the point of being laughable at times. Pour a large amount of heavy handed political propaganda and I'm sorry I contributed to its box office total.
