What is...truly...Insidious?? Time travel? Dimensional rifts? Cogent plot developments between sequels?? Now wait just uh darn tootin'... Join the McCullough and Haskins group as they struggle to diagnose a sickly sequel, one with a penchant for the spooky trills, yet tramps upon its successor's coattails, Insidious: Chapter 2, like a muffin bottom to a muffin top. Sorry muffin bottoms, but the tops have more substance.
