This was more Bond-esque than the last few Bond films...
I liked the ideas and the philosophical topography that this film only so briefly covers more than the film itself.
Some of the action sequences were quite inventive, as time was moving forward and backward (though technically wouldn't the inversion simply apply to the state of the particles and not actual time itself since we only measure time based on the Earth's gravitational rotation and as far as we know the inversion effect didn't change the Earth's gravity, so technically things wouldn't be moving backwards, particles would just be inverted).
I think that in order to accommodate the concept of inversion they made things move in reverse, even though in real life anti-matter, or negative particles from before the big bang may be inverted but they don't change the process of time itself.
Anyway, this was definitely written like it was supposed to be a very elaborate, sci-fi heavy James Bond film, without all the tongue-in-cheek goofiness. This actually would have made for a great Bond flick, because the main protagonist was written to be smart, well-traveled, and well-versed in espionage. David Washington FAILED miserably at pulling off this character, whom I didn't believe for one second was as savvy and intelligent as the role called for.
I don't know if this would have fit in well within the Craigsverse series of Bond films, but it certainly wouldn't have been any worse than the last entry. It could have also been a pretty unique first-entry in a rebooted Bond series, but it really needed a far more high-class agent who was believable as a connoisseur of fine-things and came across as rich, well-traveled, and physically capable (also, Washington being so much shorter than Debicki was HUGELY distracting, especially since the little interactions Debicki and Pattinson had seemed to indicate they had more chemistry than Washington and Debicki).
