Commendable thought process and audacity shown by J. Solanas. Although the concept of a parallel world which is upside down is completely hypothetical, the concept is enjoyable. If you are looking for some logical sci fi romance, then surely this one is not worth your time. The screenplay and the sets depicting the existence of dual gravity are awe-inspiring. There is some palpable chemistry between the protagonists, that adds on the romantic flow of the movie.
For all the die hard romantic retards, this one is definitely a catch! For the others, it might or might not suit the interest.

With Tom Cruise in the lead and Emily Blunt as the crowning glory you can definitely not afford to miss this one. New concept, superb screenplay, phenomenal special effects, all adding points to the bucket list. Personally, I can eat, watch and repeat this movie anytime.
So my take: Go for it if you like Sci Fi action and ofcourse if you go off your rockers when you see Cruise!
