Is it all bullshit or all true? Doesn't matter either way. Because you can read along without using much of your brain power if you think it's all bullshit, and if it sounds true for you then you're learning stuff about occultism. His plots might be overused, his writing is trashy, etc. etc. But it's always entertaining and full of random stuff. Plus, it's easy to read so I can finish it very quickly.
