Tum bin first part was an excellent movie.A decent love story with excellent songs and role well played by everyone.Tum bin 2 as expected is not such as the first part.Songs have been tried to repeat but dont have the same touch as the first part.Story is somewhat not that interesting.But obviously I would recommend to watch it once.If you like love story then surely you should watch.The chemistry shown is excellent with some spice of love triangle.In the end the real love survives and one has to sacrifice.
