In one sense, any review of Lovecraft's work is superfluous. You either like his stuff, or you don't. And if you are any kind of devotee of the horror genre, you'll already know which.
To be sure, he doesn't usually do the subtle, niggling unease of Shirley Jackson or Stephen King. The monsters in Lovecraft are generally described in near-anatomical detail. But that in a way is a tribute to the man: his Cthulhu Mythos is as painstakingly constructed as Tolkien's Middle Earth, and is perhaps a lot more original. Lovecraft's style is nowadays not for everyone, but his influence on a myriad of horror and fantasy writers, from Robert Bloch to Ramsey Campbell, is beyond all dispute.
The title of this collection is not quite accurate. Two of Lovecraft's best stories (in my view) are missing: The Survivor and The Gable Window (admittedly, I believe the latter was a collaboration with August Derleth. I may be wrong, correct me if I am.) To compensate, Lovecraft's verse is included - like Clark Ashton Smith, he wrote poetry as well as fiction. But if your taste in the poetic runs to daffodils and limericks, you may want to skip this part of the book.
Most of the stories are great but some do drag on a bit. There’s a lot of suspense and atmosphere in lovecraft’s writing, but sometimes not a great payoff. Highlights for me are The Dunwich Horror and the nameless city
This book is awesome. Lovecraft was amazing and this is a great collection of his works. The book itself is gigantic, which makes reading some of the longer stories a little bit on the cumbersome side. In truth I listen to the books on tape and got this as more of a reference if I want to go back over some parts of one of the stories, or if I want to read some of the shorter stories I can't find recordings of. Also for ghost stories on dark and stormy nights. I really can't speak highly enough of his works, really, if you have never read Lovecraft before and have at least a passing interest in horror/macabre tales, or even want to understand popular culture of scary monsters, you need to read some of his works.
