The reaction mostly is great. And not because it's kind of relevant for us (among the brutal barbaric invasion you became some kind of fatalist and just take a possibility to be nuked pretty ... calm) but because it's just a great movie.
In Ukraine, just for example, Oppy will back to IMAX 24.08 (not a good day for comeback, to be honest, cause there is a possibility that we would have huge missile attack from russia, but anyway ) and the 6PM 24.08 showing has more seats sold than BB tomorrow 7PM showing.
Based on reactions I've heard and read. And most of them characterized Avatar as great, colourful 3d attraction and nothing more. Unlike Gravity, Mad Max, District 9, the only aces Avatar has: great vfx and great 3d.
TDK is the main and only one reason, why Avatar (and other blockbusters after that) has gotten main Academy Awards nominations (including Best Picture).
