If you want an intelligent film about the 'what ifs' of life, watch Krzysztof Kieslowski's excellent 'Przypadek' or Tom Tykwer's 'Lola Rennt', but whatever you do stay well clear of this nonsense. At 140 minutes it is at least an hour overlong and suffers from the worst crime in cinema of being boring. Puerile humour, action pieces straight out of the Marvel playbook and inane dialogue all contributed to making this a very poor effort.

Many reviewers have stated that the central premise is original, which just shows how little science fiction writing they are familiar with. Even 'Family Guy' did a much funnier job with Stewie and Brian's interdimensional antics.

How this mess was worthy of 7 Oscars is beyond me. I'm off to watch 'Lawrence of Arabia', 'The Godfather' and 'One Flew Over The Cuckoo's Nest' to remind myself that there was a time the Academy recognised craft and talent.

One last thing, this film needs a warning for people with photosensitivity, which was not on Amazon. There are several almost subliminal sequences which could easily trigger a seizure.
