Thanks Ayako!
Alistar Harkness has a short review in The Scotsman for Side by Side in their short piece on films opening this week. In addition to mentioning some of the highlights in the film, he says that:
KEANU Reeves proves a surprisingly engaging host for this documentary inquiry into the ongoing transition from celluloid to digital filmmaking. Chatting to an impressive array of pioneers, converts and digital doom merchants (well, Christopher Nolan), Reeves gets into some animated discussions with the filmmaking A-list that help make in-depth tech-talk about relative merits of photochemical processing, digital manipulation and light-weight camera rigs sound a lot more enthralling on screen than they do on paper.
