Life is Beautiful has the signature Sekhar Kammula touch with an emphasis on human relationships. And yes there are moments that tug at your heart strings and yes the scipt is high on nostalgia.
However one can't but constantly sense the similarity with Shekhar's earlier film Happy Days. The sub-plots and the music clearly remind one of his earlier outing.
Also Life is Beautiful, with a running time of 2 hours 45 minutes is too long. Overall, it's decent but not a classic. One can watch it for the sentiment and the middle class values it portrays.
