I've avoided 3D movies since the 70's. Bad auto accident screwed my eye sight to a point where those old time 3D (paper) glasses wouldn't work. But, being a sci-fi nut, I just had to see this movie. Standing in line for the tickets, you had the choice of three variations of this movie. 2D, 3D, Imax tru3D. So I just took a chance and went to the 3D version. Coarse, the glasses cost ya an extra $3, but I was pleasantly surprised. They worked! The new & improved 3D technology is pretty good. Oh-yea...thoroughly enjoyed the movie. Word of wise..leave all your political/tree hugg'n feelings at the door and just enjoy the ride.
