Whats with this current remake obsession? Why does it have to be remade? Theres "reboots" now of films that came out ten years ago.

Who would play Newton's/Bowie's role? I can't think of anyone who could play that part so well.
I'm also puzzled by your desire for a simpler film ("less non-linear and avant garde") when it's already pretty straightforward. I suppose the wonky Martian train could be improved, but often Hollywood production values add surprisingly little: look at the remake of 'Solaris' or else 'Dogville'. (The latter was filmed on a black soundstage, with the streets sketched in paint on the floor, and the houses represented by a few free-standing doors and window frames., "Dogville" could have been a brilliantly shot film of a play. I'm not convinced that the approach was an improvement on good, conventional films, but I'm glad the director tried the idea.)

"If you ain't a marine then you ain't beep

Sounds good to me. Could end up really interesting. And since film technology has come a long way since then I think they could really wow and make it look even more sci-fi then the original.
