The difference Christopher Nolan would have made

Rating: 4/10 (25 November 2017)

The writer/director has had a reasonable and interesting concept but didn't have the writing or directorial skills to pull it off. This would have been so better given to someone actually with talent in those areas.
Most of the negative reviews do correctly identify the downsides to this film, except the ridiculous one pulling is "misogyny" when it's non-existent. I'm not going to do a synopsis of the issues as others have correctly identified them.
For me the summary is a film that passes time, has interesting concepts but was a wasted opportunity because of poor execution and writing.
