Watch the film once just to experience it. Watch it again to look for things in the background, scenes that you weren't paying attention to the first time around, this time with the power of hindsight to better understand why things happened. Watch it a third time to refresh your memory and purge misconceptions from your head put there by people bitching about inconsequential details of a work of fiction not meant to be taken seriously. Repeat steps for use in future debates.
It's scheduled for a 2018 release but I haven't read about any fixed date yet.
"Movies are the enemy of the novel because they are replacing novels. Novelists shouldn’t write for the movies, unless, of course, they discover they’re no good at writing novels." - John Irving
