I liked the premise of the story. A much better usage of the idea than the dismal movie Next. (Poor Phillip K. Dick wrote some phenomenal stories, which have been turned into a few movie gems and a whole lotta crap) For me though, the reason that movie sucked is that the way the premise was portrayed there was no tension whatsoever--he dies on screen all the time in his future visions and just undoes it immediately, even to the extent of bullet-dodging. The only way he would ever be in danger is what the movie puts the second half into (because for the most part he can only see 2 minutes ahead), but then cheapens that by taking it all back.
Anyway, back to this story. So I liked the premise. I thought the reveal of the relationship made it feel very real. I like how his vision is a little different than most I've seen in that trope--I don't remember seeing one that's so cemented in a place rather than following a certain person or something. It made the character's actions make a lot of sense, why he sits in his dorm room by himself most of the time because that is his safe place that is kept uncluttered by being devoted to his quest of solitude.
It kept on annoying the logic centers of my brain, though, particularly the fact that the love interest is so solid. I mean, our main character can see branching possibilitiies from the tossing of a bean bag, so clearly what he sees is not only influenced by conscious choices but by random perturbations. So, is this other guy somehow immune to the powers of chance? Does the guy never trip, or get sick, or anything else that would skew his actions in any way no matter how momentary? Does this other guy have no internal thinking that could associate with branching paths? So for the whole story I was trying to figure out if the guy is also somehow supernatural, made of probablistic adamantium which cannot be affected by the waves of chance all about him and so rigid and robotic in his thinking that in any given circumstance he would always do the exact same thing. The story didn't seem to have any explanation, except perhaps for the steadfastness of the protagonist's choice, but that is only a partial explanation, to my mind. This question drove me to distraction and there was never even an answer.
