I came across the trailer for Samsara having never heard anything about it before, or the filmmakers involved, but the trailer alone made me want to check it out. I got to see it in IMAX and I'm glad I did as, as everyone else has said, visually it is stunning, so the bigger the screen you can see it on the better.
I have never seen Fricke's previous work such as Baraka so I had no idea what to truly expect when I sat down before it started. I see people have mentioned they got bored after 30 minutes due to the lack of dialog/narration and that overall it's too long but I couldn't disagree more. From the first scene to last, I was totally engrossed in the visual and audio experience. The juxtaposition of concepts and themes worked, I got to see places and activities I didn't know about in a way I have never seen before. The soundtrack is spot on, capturing and switching the moods perfectly. It moves you.
I see critics have said that the message of Samsara isn't clear but I don't think it needs a message. Seeing Samsara has enhanced my understanding, and appreciation for, the way our world is and works, and what really matters most to us. How many times can you go to the cinema and come out a more knowledgeable person?
Samsara is quite simply a work of art and, like all great art, you interpret it in your own individual way and it makes you think. Do yourself a favor and experience it.
