I bought the Blu-ray set a couple of years ago and finally got around to watching Close Encounters of the Third Kind. Since I hadn't heard of any generally preferred version, I chose the original theatrical and look forward to checking out the other two in the set when I get some more time. The special feature on the disc to tell you when scenes are different and how they're different should make the comparisons a bit easier than with something like the Blade Runner set.
Despite having a few of the big moments spoiled for me beforehand, I still went into the majority of the film blind and was glad for having done so. The effects and models were stunning and the unusually high amount of Spielberg's People Looking™ shots were definitely earned. I won't say it went way beyond my expectations, but they were pretty high to begin with. Seeing this and reading the E.T. thread on the boards are going to make me buy E.T. on Blu-ray and re-visit it for the first time since my childhood, when I didn't actually care for it that much.
And I may be crazy, but was I hearing things or did the mothership play part of the theme to Jaws at one point?
I also just watched The Last Unicorn tonight with my wife. It was cute. But as always happens in Rankin-Bass Productions, some of the slow, folksy songs made it drag a bit for me. I give it props for being a less-than-conventional fantasy story though. I can see why some people really like it.
