I saw it last week and enjoyed it, though it has been over-hyped in my opinion.
The soundtrack was excellent, as was the three younger kiRAB, the cinematography and the direction. However, it got a little repetitive somewhere in the middle, though it did pull itself back quickly. I also wouldn't call it the "feel-good film of the year", but there you go.
No, it was good. I give it 4 stars, but I was expecting something unforgettable, and the only thing that stays in my head is the cinematography, which I thought was brilliant.
