Challenge of Thought
Straight-up, this is one of those movies that plays with the mind. Very thought provoking and often confusing, it's a thrill ride to watch alone in the dark at 2 am--amplified effects. I enjoyed it thoroughly but often found myself confused. My theories were often crushed then resurrected.
This is the original version, before the Tom Cruise Hollywood remake known as Vanilla Sky. The lead actors in this were excellent. A taste of Spanish culture, nightlife, and beliefs.
I'd recommend it for anyone in the mood for mind games.
