Despite being a space anorak, I was disappointed. At around 35mins per DVD, it's clear they'd all fit on just one - it'd be a good deal at 1/5th the price. The packaging is basic; no further content or data on the cases. And cheap-looking DVDs...Content is fun, but only fascinating in part. About what you'd expect from a decent TV documentary. The IMAX format is lost even on my widescreen setup, and the resulting wide-angle distortion is sometimes a distraction.Tech note: I also noticed poor colour resolution - distinct colour graduations which I've not seen on other DVDs. Perhaps a coincidence, but I doubt it.Very disappointing. Sorry to be curmundgeonly.
