Watching this movie was completely a different experience...pay attention to each detailing...there's a lot to be realized...please be aware of some of terms in physics like, time inversion, entropy, 2nd law of thermodynamics before watching the film...the climax was really awesome...like Nolan's other films if you're looking for something spoon feeded, then, this may disappoint you... But if you're willing to think beyond horizon and make your own conclusions, this will truly amaze you for sure... And the climax opens up to new possibilities... Which is really thrilling.... And you'll love this for sure...
