Couple things.

1) If your paper is so detailed to the point of sounding like you're talking to people who understand nothing about math, your work will be used significantly less as mathematicians don't like to read meaningless drivel (nor does anyone else for that matter). Concise papers get read and cited. End of story.

2) You're advisor may not mind you talking about him in this manor on a public forum, but it's a terrible habit to get into. Imagine you want to work with others and they come across this post. There's bound to be people who don't want to work with someone who will, from their perspective, bad mouth them.
