Personally I don't see the reason to include you view in the introduction, maybe I'm mistaken.
Somebody help please! :)
In a prompt like this, you should mention your opinion in the introduction and further ellaborate it in the conclusion paragraph.
Don't make your opinion a surprise especially if it is being asked.

hope this helps....
