How will Trailer Analysis Help me?

I think that trailer analysis has really helped me get a good grasp on the codes and conventions meaning that I know have a good understanding of how they are used and how they can make my trailer better. Furthermore this has also meant that I have a better idea of how trailers are edited meaning that I can use this to make my own trailer. Also I it has given me a good idea of what sort of shots that I can use in my trailer.
