Ceticultsot Beautiful, moving film.

Lollivan It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

Sarita Rafferty There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

Roxie The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

trimmerb1234 Was a comedians famous catchphrase and here is what makes this popular science documentary so distinctively good. From the clear structure to the individual well-chosen contributors to the narrated script (uncredited), it was not just very lucid but engaging even compelling story-telling, the entire production done with artistry. The sense of awe, majesty and mystery which Patrick Moore's Sky at Night opening cleverly evoked, is the tone and standard yet does not compromise the solid science communicated throughout. It gives proper weight too to historic figures in astronomy using archive film clips. It is a demonstration and reminder of how science documentary-making can both be an art as well as science.I have to contrast this with the tendency to simply dispatch a (the?) popular TV scientist in a hire car to tour the USA, dropping in all over the place for a coffee and to listen with a camera crew over his shoulder.
