For what it&#x27;s worth, and having read the book, I went to the movie knowing that a few of the key plot points were based on dubious science. But I still enjoyed myself quite a bit. I had to go to a 3D showing, and that was very distracting. In 3D, a lot of the beautiful Martian landscapes looked distinctly odd, with the little rover sticking out as looking very toy-like, like those tilt&#x2F;shift photos you see that deliberately make a real scene look like a model. While the 3D effect on the &quot;beauty pass&quot; shots of the spacecrafts were gorgeous, the effect of being, apparently, inches from Jeff Daniels&#x27; age-spotted forehead was much less so. So personally I&#x27;d recommend the plain old 2D version.
