Well I haven't seen Interstellar but I didn't finish Whiplash - the 'not my tempo' bit was too uncomfortable and didn't really ring true. I listen to music like that sometimes, I often think I can tell in a second or two what's right or wrong, but in practice tempo just doesn't settle down that quickly, it's something the player has to find over a bar or two. Maybe he was just fucking with the kid but I didn't want to watch that movie. Also, the sound mixing was stupid, everything went through the centre channel when it was a glorious opportunity to put us right in the middle of a band, surrounded by energy.
