The casting was perfect. Relatively unknown actors who portray the relatively unknown facts and situations in India's slums. Great. :)
I love how this movie opens up the eyes of the people who watch it (like myself) and raise awareness that yes, these things do happen, and they exist. The story of how the sheer will to survive and to pursue a love is really touching, and at times, really heart-breaking (like when Jamal gets tossed out of the hotel by his brother). His courage and intelligence is quite beyond understanding, and I believe he embodies everything great about the human spirit: courageous under duress, resilient under opposition, and able to love when all hope seems lost.
The victory of humanity shines perfectly in this movie. :) My only regret was not seeing this any earlier.
One of those movies that have to be in the 'greatest movies' list. Watch it however you can; no regrets whatsoever, I promise. :) Love, drama, action, suspense, horror, adventure, and some epic Bollywood dancing (really, what Bollywood movie is ever complete without the group dance?), Slumdog Millionaire has it all.
