It took some time for that line to sink in; as well as the tagline "The future is history".
No other movie has ever shown a concept of time travel as complex as this one. It almost blew my mind trying to assimilate it.
Brilliant. IMHO The best SciFi Movie ever made - Even better than "Blade Runner" or "The Matrix".
