Christopher Nolan does sci-fi... to which I feel like saying to this hitherto great director, don't bother! The cinematography is great but that's about it, otherwise it's like 2001, Blade Runner and Star Trek all thrown into a blender with a shot of gratuitous emotional hysteria carved out of a soap opera sub-plot, or perhaps left over from Ann Hathaway's Les Mis histrionics. Meanwhile Matthew McConaughey croaks away like some Field-of-Dreamsesque sharecropper catapulted into space for no obvious reason like it's a case of mistaken identity or something. Way too long and all but the most hardened space cadets will bale out before re-entry.
