Poor Dialogues in the second half

The dialogues in the first half were excellent and had the audience laughing and bursting at their seams. Dialogues such as the one in which Shahrukh rebukes his father about his habit of chewing tobacco which stunted his sperms, and therefore he became a dwarf had audience roaring. However, in the second half, the dialogues were poor and sparse. There were no light moments, and it seemed that the second half was not directed by the same Director who had done his job so well in the first half.
