David Dhawan is a far better director. He always adds more humor into his movies than Rohit Shetty and the action scenes are not over top. His movies often have the same formula but he handles them very well. Most of his comedy movies that he has done with Govinda and Salman Khan are more entertaining than Chennai Express and the Golmaal franchise.
Deewana Mastana, Bade Miyan Chote Miyan, Jodi No.1, Shola Aur Shabnam and Judwaa are his main movies that i like while rest he did with Govinda and Salman Khan were good to.
