It's one of those mistakes that Movie Franchises have. There is no need for sequels if the story is already done.
Insidious featured a solid and very scary first movie (6/10), an improvement with a very interesting second one (7/10) and another solid entry as their "prequel" third movie (6/10). This 4th installment was just not needed.
The Story is predictable, except for Lin Shaye's Elise no character can really shine and the humor is disgustingly bad.
There are some okay jump scares, but they offer nothing new and are just there because they need to be there.
It's not a complete failure, but if you are no fan of the franchise, this movie is not for you.
4/10
