I liked it. The performances and visuals were very very good, and the major incident eating at Robert's core is very effective, so is the inciting one, but I didn't really like the reliance on and execution of the editing as the film moved forward. That and the visuals are pushing us and I feel the visuals did most of the heavy lifting there. That quick, staccato motif in the editing for his dream-state felt directorially trite and the ending hammered itself home a little too much for me. It became platitudinous after awhile.
And It felt like they had that ending of going into the city planned but didn't really know how to get to it organically. I enjoyed that juxtaposition from forests and farms to a theater, office buildings and a mirror as a standalone moment though.
I may have enjoyed it more overall if they cut some of the narration.
