Insidious: The Red Door is the biggest horror movie of 2023 so far

Also, the film had very poor critical reviews, including a 39% Rotten Tomatoes rating. But then, critical reviews aren't exactly the determining factor for box office success so there is that to consider.

Given its debut gross of $31 million, which was enough to knock Indy off the top of the box office, maybe our surprise is misplaced. But then, we didn't see the film competing beyond that weekend given the release of Mission Impossible 7 the following week and the Barbenheimer craze in the week after that.

Even if the critics disagree, the fact that it managed to do these numbers despite all of these obstacles is a testament to its quality.

However, there are still a few big horror titles on the way and they could very well threaten The Red Door's crown. The first of these, titled The Nun II, will debut in cinemas on September 8 followed by Saw X a few weeks later, on September 29.

The final big horror release this year is Exorcist: Believer which will arrive on October 13. With these films on the way, The Red Door has a big fight on its hands if it is to retain its title by the end of the year.

By the way, an Insidious spinoff titled Threads is currently in development. The film will star Kumal Nanjiani and Mandy Moore with Jeremy Slater, of Moon Knight fame, at the helm.
