Jeremy of The Media Stomp wrote, "Director James Wan manages to make a decent PG13 horror movie out of Insidious. It's not perfect by any means and its not exactly great material, but it certainly has its moments. The main problem with this movie is that it doesn't seem to figure out what it is. One half is your typical horror movie that relies heavily on quick scares and jumps and the other half tries to be campy and funny. Insidious never manages to achieve perfection in either category. Had it stuck with trying to be one or the other, I think this review could have ended up being totally different, but it didn't so you are given this middle of the road review."
