Some interesting points (e.g. the interpretation of The Music of Erich Zann), but mostly the analysis seems forced, arbitrary, even comical at times (e.g. The Colour Out of Space). Airaksinen keeps making unfounded claims like they were obvious to all. For example, he claims Cthulhu is "nothing to worry about", that Armitage "has never seen Yog-Sothoth" (which, according to Airaksinen, would somehow ruin the ending of "The Dunwich Horror"), and that the Elder Things "look like Cthulhu".
Peter von Bagh used to call academic cinema studies "swirling around piss in a bottle", and at times I was reminded of that while reading this work. There is no empathy or human connection to the man struggling to be heard behind the words. Airaksinen's attitude seems arrogant and disdainful of Lovecraft, which is perhaps an even more irritating pose to strike towards the subject of a book length study than uncritical worship. There is a constant air of smug condescension, as if Airaksinen thinks he can infallibly dissect this human specimen called Lovecraft. He keeps using adjectives like "childish", "immature", and "stupid", which to me does not seem like a sign of a serious scientific study.
The inner structure of the book is also quite confusing, and at times seems even random.
