I'm a fan of the genre and this flick is well put together. The main character is totally believable, impregnated in his quest, dialogs and other characters are on point aswell. The plot & the atmosphere keeps you captive throughout untill the ending which is jumpscare (and i hate jumpscare).
In other words i expected a much better ending with the blinkman and answers which we do not have: why the need to not blink to see him, is it some demon or something else etc. It could have drifted to horror genre in the end and doing so be much better imo..
6 stars that's what it's worth really; rewatch value..maybe
