The Revenant is a long endurance movie. The story takes its time to unfold and the focus is more on the cinematography and set pieces and the performances from the two leads. If you go into this expecting a compelling story or great dialogue this probably isn't the movie for you.
You should definitely check it out yourself and develop your own opinion on the film.
I disagree with the idea that is a long endurance movie. It opens with a pretty stunning action scene and has at least five over the course of the movie. Of course, it is a long movie but the pacing isn't particularly slow...it's just that there is a lot going on.
I thought The Revenant was solid but fairly unsubstantial and falls victim to one of my greatest movie pet peeves (which I won't spoil). I've seen four of the eight nominees (Fury Road, The Martian, Bridge of Spies, and The Revenant). I didn't hate any of them, but none of them were truly sensational films. I plan on seeing The Big Short some time over the long weekend. I would absolutely love to see Room but don't think I can see it anywhere where I live. Have no interest in seeing Spotlight or Brooklyn, as I've heard bad things from the people who saw them and both seem like sanctimonious lefty films.
