I watched the remake of The Day The Earth Stood Still yesterday. I saw the original in 1951 when I was 9 so I do have something for comparison. The remake has a lot of plot holes and unexplained loose ends but only if you've seen the original. Naturally in '51 there was no CGI for special effects so the producers relied heavily on that technology this time around. I personally prefer the original release version. Watch both and decide for yourself.
