Big Nolan guy, but this just wasn't it. Too much focus on the mind-bending time concept, less focus on character development. Also, I could barely understand what the characters were saying in between the ventilators, whiplashing cuts, and chewing. Wish they had subtitles on.
Also, this may be an unpopular opinion, but Washington seemed too one-lined. Not a lot of depth in the character or the way he delivered. Perhaps this was by design? Came off as dull to me.
Worth watching once this comes to HBO/Netflix.
