  To be honest, sci-fi isn’t my favourite film genre, but if I had to pick (which I do), Back to the Future is the one that springs to mind.

  Mate.
  How long have you got. I love ALL of them.
  
  Flight of The Navigator is fun.
  Primer is good. I liked Interstellar and Arrival.
  Looper is also good. I like scifi films about time travel and loop holes. If you have any suggestions for me, leave a comment.
  
  AND VOTE FOR ME. TEAM LEADER!

  IF you haven’t seen the film Arrival yet, find a way to go back in time and watch it at the cinema. ALL THE FEELS.

  I like space films! I really liked Interstellar, and Contact, and I agree with Emily and Antony – you should see Arrival if you haven’t already.
