Ralf’s review published on Letterboxd:
Radius starts off as your run-of-the-mill thriller with a twist and then slowly but surely takes on a completely different direction, which came across as truly unique or at least unexpected to me and it's also putting an interesting spin on the story we witnessed beforehand and puts everything into perspective.
If you stay with it during the slow build-up "detective story" aspect of "why is this happening?", you will be very much rewarded later on, when the film starts probing the question "who is this happening to?".
