The really negative reviews I see confuse me. I haven't had to provide any information to access the articles I've read. They seem to be balanced and carefully written to avoid an "adamant" stance, so that anyone reading the article knows they also need to read other stuff. They use articles published in peer-reviewed journals as resources. The articles are very readable, making them more accessible. In general, I've been very pleased, as they give me insight that I can then verify with other resources.
