It's well made but the sound definitely needs more work. The voices are unbalanced, unarticulated and therefore hard to understand. Especially those with an effect on it. The robot is way too distorted and loud, and he's speaking all the time, very annoying. And I feel, there is too much compression. The sound effects overlapping the voices are too loud too.
Makes the movie unwatchable for me unfortunately. If you'd fix it, it could be a solid 5 stars.
