The series is on the sympathetic and charitable side in terms of tone and analysis, but it still gets to most of the major problems, so its probably a good resource for referring to people that want a "serious", "non-sarcastic" dive into the issues with LW and EA.

Edit: Reading this post in particular, it does a good job of not cutting the LWs slack or granting them too much charity. And it has really broken down the factual details in a clear way with illustrative direct quotes from LW.
