Saw this last night, that 'derezzed' tune really made me think of the 'Escape from New York' soundtrack, infact a few bits sounded like John Carpenter doing Vangelis.
All fair critisisms above I'd say, but I just like all component parts, and I think them doing the soundtrack makes sense (both ways) beyond what they brought musicaly.
The film looked really nice, when I first saw pics of it, I was kinda dissapointed how sharp and glossy it looked (which again was probably required for the whole HD 3D thing), I was hoping they might do someting a little more retro, but I liked it. All the cloud and mist, and the rocky 'off grid' areas helped balance out the shinyness. The exterior lighting was especially beautiful, made me think of John Martin's engravings. Just a shame about the shit Star Wars cookie cutter storyline..
