I think this movie is gud for inspiration.salman is a very good actor songs are also gud story line is also very nice but somtimes coping someone is not a right thing.As we know that brothers concept is also the same as shown in sultan.
In Brothers the name of wresling leque is R2F( Right to fight) and in sultan name of wrestling leque is pro take down.And the concept of fighting in both the movies are the same.As we saw street fighters in both the movies. So I thing coping someone is not so good.
