The first thing that you would probably feel at the end of the movie is - The movie was Strange. The movie basically doesn't have a "real" story as in nothing really happens. I would liken this movie to something very loosely on Easy Rider. The protagonists in that movie were on a trip to Mardi Gras, here the Mechanic is searching for a Mela. They encounter few people on the way, they reach the destination and the movie ends - to put it in a oversimplified terms.
This movie does contains few moments of subtle laughter - but doesn't give you enough. The scene with the local water don is quirky and it seems that the movie is going to change some pace - but it is left at that.
Abhay Deol seems to have carried his Dev D attitude in this movie which sometimes feels like a misfit. Satish Kaushik's character as the Mechanic is the best cast.
May be few years down the line this will be termed as a defining piece of work in Indian Cinema - Bollywood does needs to change its face to catchup with the global scene and not be a laughing stock with its song and dance sequences in huge bungalows. This just might be a baby step towards that direction.
