This is presented as an Indian format satire, the acting deliberately bad, the songs and dance the main thrust, with the kiss being "adult" content in India. To most westerners this is not a very good movie, but if you look at the Mike Meyers "Austin Powers" movies you will see the same deliberately bad performance, just without the song and dance.
The actors are playing for laughs, the story is written and directed to be an outside of India satire and farce, and on that level, it performs.
It is good for a laugh if you can accept the satire premise, if not, avoid it.
