Surprisingly enough, in most of his stories, the chaos from outside is contained. Notably in the Call of Cthlhu, The Dunwich Horror, and the Case of Charles Dexter Ward, where people spring into action once the threat has emerged. The difference between Ghostbusters and Lovecraft's work (outside of being a comedy) is the reaction. In Ghostbusters, they're presented as flawed noble heroes, striving against everything to defeat an evil. In Lovecraft's work, they're presented as individuals who are doing what must be done to contain the ever-present threat. The difference between Gozer and Cthulhu is that Gozer is a one time threat, whereas Cthulhu is always there.
