For anyone that's seen Heima, INNI is nothing like it. It's minimalistic, enchanting, a film of simple visuals with inserts from the band's past and it is all about the sound. I recommend seeing it at a theater on a big screen where you will feel like you're in the middle of the most spectacular concert. Your mind zooms out and the loud music takes you on a memory trip and rips your chest apart. It might not be for everyone but the lights and the images are so gripping they'll most probably send you into a trance. Those who won't like it won't finish watching it, however all the people at our theater had their eyes glued to the screen the whole time though. A beautifully done concert film in my opinion.
