I think I've found the perfect film for Blu-ray - the one it was absolutely made for. A brilliant film - not really a children's film in any sense as it features death, loneliness, oppression of a senior citizen and attacks by a pack of dogs. The overriding theme is loss. However, for adults who have an open mind, this is a genuinely up lifting experience. There are two reasons why I say this the perfect film for Blu-ray. Firstly, it's the best and most detailed transfer I've ever seen, with an astonishing amount of detail and excellent contrast range. I don't have a full surround sound system, but the soundtrack seems to make full use of the frequency range (my Rel sub-bass speaker was certainly working). Secondly, the aspect ratio is 16:9 or as near to it as makes no difference. This means that the picture fills the whole screen. I'm certainly not one of those people who would stretch a picture to fill the screen, and I'm not averse to having black bars ...
Sometimes a grumpy old man, at others middle-aged but not past it yet. My blog title is a quote from a 1970s Doctor Who story - and, by the way, there is no pause before "probably"! That's the genius of Tom Baker's timing.
