Pre-production unit: Investigating Superhero scripts

Recently I have taken it upon myself to investigate the superhero genre, and also invest in some super hero movies so that I can get a better idea about how the genre has been treated and filmed over the years. A movie series I have been investigating a lot is the xmen series, and so I some of the xmen DVDS to watch and make some notes on. I also checked out one of the xmen scripts online so that I could read the script and see how the director interpreted what the script writer had written. It is relatively easy to find movie scripts online, and the one I read can be found here.

The collection of Xmen dvds I acquired for research.

I have noticed that alot of the super hero scripts I have taken a look at are very on descriptive details.
This would of course be beneficial for a director, but sometimes the amount of description used seems quite redundant. For example, on the 2nd page of the script I have linked to in this blog post, this is written:

"A LITTLE BOY. A boy who will not die this day. A boy who will live to see the end of the war and the world of the future."

A lot of the description is written almost like a sentence in a story book, and not at all like directions in a script. I am not sure of the purpose for the script being written like this, and I put it down to the writer's personal preference and style, but I feel that this type of writing would hinder the director's ability to properly absorb the important information I will be writing in my script, and as such I think it would be best if I were to keep my scripts as concise and to-the-point as possible.
This should help the director understand exactly what I as a script-writer would like to convey in my story.
