Went to see it again tonight, however rather than last night's state-of-the-art Vue cinema in Westfield, this was in a last-gasp Odeon in Guildford. The difference is night and day. I never realised what a difference a cinema could make. The fight scenes looked like they were filled with shaky camera angles which was down to the much, MUCH smaller screen, the brightness and contrast were much lower than in the Vue cinema but the biggest difference was the sound. Honestly it felt like going from that old-school THX sound to an FM radio. I never realised what a difference it made until I watched the same film on two different cinemas back to back.
I'll definitely be factoring this in to my future film bookings!
