I had never seen 'Close Encounters' before, so my purchase of the Blu-Ray release was something of a blind buy except, other than a positive review I glanced through on highdefdigest. I don't even know anyone that has seen it, so was getting curious because of the revenrential terms in which the film is described. Having just finished watching it about 15 minutes ago, however, let me just say wow. If you haven't seen the film it's very intense and has aged incredibly well. The special effects don't break the immersion (as happens sometimes with older effects-laden films) and the acting is great. I was totally sucked into the scenario... I read in the supplementary material included that Spielberg believed at the time that UFO contact had really happened in the 20th century, which makes sense since there is an amazing sense of realism to it. This is definitely not the recent 'War of the Worlds' film or 'Independence Day'. Basically, if you have not seen the film before you will not be disappointed by it; you can afford to blind buy this one.
For people who have already seen 'close encounters', I should mention that this includes three versions of the film, all three of which are in 1080p... the theatrical version, special edition, and director's cut. There is lots of printed material (a booklet and a small timeline poster) showing what the differences are between the various cuts. For £14, you get more than you do with a lot of Blu-Rays costing £25.
Picture quality is a huge pleasure to behold. The film is definitely nicer in high def. I was really impressed at how good it looks for its age. While not every scene is a showcase of what 'high definition' is, anyone could see the difference between this and standard def DVD. 100% recommended on picture quality.
Basically, I went from knowing almost nothing about this film to prizing this bluray as one of the best in my collection. A wholehearted recommendation which, at this low price, deserves to be on everyone's shelf.
