Could have been better with an emotional core of relationships revealed - we can't care about this poor guy bc even by the end we know little to nothing genuine about him.
They stuck too close to the claustrophobic immediacy, and gave nothing to relate to. So this particular shlub gets no significant back story, and therefore we don't care. We can't!
And from even the first few frames, you'll know if you'll like it or not..
