I just watched this on HBO this past weekend. That was 2 hours of my life that I'll never get back. Fortunately I'm retired, so I have plenty of time. Unfortunately, I found very little to recommend in this movie.
I read a number of other reviews that talked about all of the violations of the laws of physics in this movie, so I won't go into them here, but the one that bothered me the most was his propelling himself through the rings of Neptune and his not being stopped by all the particles hitting the shield he was holding. I still don't know why he had to do that anyway. I might have nodded off and missed it, but I didn't see why he could just take the shuttle that he flew to the other station with to get back to his ship.
There's next to no story and almost no action or suspense. Most of the movie is spent listening to Brad Pitt's character, Roy McBride, muse about his life and the nature of being. That could be the makings of a good story, but his thoughts are either too esoteric or uninteresting to provide any sort of lesson or insight.
There's almost no action, The pace of this movie is catatonic. There are about 3 or 4 sequences with action, but besides most of them being physically inaccurate, even those are shot in a way where it's hard to see what's really happening and they don't add any interest or ever go anywhere.
Donald Sutherland and Liv Tyler are totally wasted in this movie, to the extent they have roles at all, and Tommy Lee Jones' character, while critical to the story, does little to build on or resolve any of the questions from earlier in the film.
Overall I find very little to recommend this film, other than perhaps some of the shots of the planets are truly beautiful.
