I liked it. It held my interest. The criticism by Emily Wilson saying the movie lacks emotional nuances and the like may be true -- I've never read The Odyssey so I can't tell. It's far from my favorite Christopher Nolan movie (that would be between Memento and The Prestige, two of my all-time favorites, and Insomnia is also pretty good). But it was a good tale.
I've heard of people walking out because they thought it was too violent. My neighbor said friends of hers left midway because it was too gruesome. It was violent in the sense of a lot of people dying, but with the possible exception of a giant chomping down people like they were pieces of salami from a charcuterie tray, it wasn't much more gruesome than an episode of Star Trek.
I've seen some people complain about casting Matt Damon in that role. I guess I would have preferred Christian Bale, who would have done a good job, but Damon did OK. And of course I have no objections to the casting of Lupita Nyong'o or Elliot Page.
