I was in the mood for a heavy art flick, so I was already bracing myself for a lot of languid pacing and droning shots. Luz definitely scratched the itch and aesthetically I really enjoyed it. It feels very much like vintage Cronenberg, using 16mm film and a lot of well framed slow pans as well as a wonderfully moody synth score.
The way the narrative is expressed is vague and nonlinear. I realize this is part of the overall style, but can't help but feel it was taken a step too far. I'll admit I lost track of what was going on at points, and it was only through digging online and re-watching scenes afterwards that I was able to piece it all together. It's aim isn't for "anything goes" surrealism, there's actually a cohesive plot that's steeped in horror/sci-fi tradition, you just gotta do some work to put it together. If you enjoy unravelling riddles, this might be up your alley, but I personally prefer films you can decipher on the first watch. At only 70 minutes, there certainly was room to spell things out a little bit without fully loosing the abstract edge.
I've heard this was a student film, if so, great work, keep it up! I love your vibe, but can you help me out and explain things a little more next time?
