Time travel is one intriguing & interesting subject. It just has so many bits & pieces that when put together seems like one complex puzzle. Cinema of course is the best medium to highlight the complexities of time travel & the surprises it brings with it.Hollywood has been making many time travel films since the 50s most memorable of which is undeniably Back To The Future. I love Back To The Future it never gets old!!! Although the story is so complex it is seamlessly integrated into a delicious pop-culture sandwich which actually is very simple to grasp.
