At the time of purchase I found 17 quid a bit steep for an 18 year old film being released on Blu-Ray for the second time! Nevertheless it has been one of the best buys of this year for my collection. Warned off by negative reviews I did not buy the previous transfer, so I cannot compare, but can confirm that this release has phenomenal sound (6.1 DTS HD Master Audio) and very good picture quality, particularly in close-ups. It contains 3 versions on one disc via seamless branching (why, oh why can't all BDs with multiple cuts have this?). The best version for me is the middle one, the extended but not "ultimate" special extended edition. One addition in the longest cut is footage of the T-1000 searching John's room, take it or leave it. But the most dramatic addition is a different ending which actually makes Terminator 3 and upwards impossible in my view!
But then the "Terminator" franchise has never worried about things like this. T-2 just suddenly announces in a Sarah Connor voice-over at the beginning that 2 Terminators were sent back, not one as stated in the original "Terminator", and no satisfactory explanation is ever given for this change to the story. I guess most people don't care because they liked T-2 so much.
It is a classic 90s action film, and has not dated badly at all. I notice on Amazon that some people have had technical problems with this disc. If you have a Profile 2.0 player and have installed the latest firmware there should be no problems. I found that the disc loaded in reasonable time (given the fancy menu and extras) and I had no problems of any kind. Always having to type in a code to view the long version is quite silly, but I would recommend the second version anyway.
This release could stand to be a bit cheaper I think, but it is undeniably a must for "Terminator" fans.
