Thanks Cas
Because people like me are useless at saying no, and i cant resist if the new audio track is DTS-X/Atmos.Just realised I have the 3D blu-ray of this in a compilation box I got for a couple of quid and never watched. Might give it a go tonight.
This has been bargain bin movie for ages though - I can't see why anyone would drop 20 quid on the 4K. It's also a strange release when there are so many much better movies still not available on 4K.
