Oh and also what you define as 'great' pictures.

You see, you will think that high definition screen is the best and awesome and all that jazz.
But do you know that the make up of the actors have to be improved along with the high definition, because!!! High Definition means you can see every tiny witty bit of blemish and imperfections. I am not sure how you enjoy zoom in scenes with face full of... pores? Even though it is a very normal thing, it just somehow turned into 'scientific photo' for me.

I think it is even more impressive to produce a good work by a less than awesome product rather than vice versa.
