Bookmyshow is a very nice site.
It is specially a online movie ticket booking site. I can get every information of movies which are going on in cinema halls. Even I can see the movie ratings here. So it is easy for me to choose which film I should watch and which not.
I can search cinemas as well as movies in this site. They give all the information about the cinema halls.and provide the correct time chart of whole week of movies which are going on in that cinema. Even they gives the exact location of the cinema hall.
Here I can book exact movie seat which I want as the provide a diagram of seats and screen so I can select proper seat with best view.
Overall it is a very nice and helpful site.
