This is good news!!!
I saw Ken's Gaudi film at the superb BFI tribute to Ken in London last year. Ken's Gaudi film is short (15 mins) and conventional and respectful. The interest is in Gaudi and not in Ken. If someone doesn't know Ken's documentaries I wouldn't recommend this, but for the Ken fans it is great to have another work on DVD.
I've only seen it once, and memory sometimes plays tricks...
