Hello! I'm a 'noob' in philosophy, I'm trying to get into it.

I started with Meditations by Rene Descartes and I was wondering what is everyone's general feelings towards him? I find him a bit full of himself and difficult to read, but I'm quite probably the reader he warns doesn't like. That being said, my question is:

What are questions you'd ask him if you could, in regard to his meditations?
