Insidious is the best horror franchise I have ever seen, all of the movies in the franchise are great and got a genuine and unique scare in them. but it isn’t always the smoothest franchise to follow and master. I know the general concept of the franchise and I am a horror buff, in the movies, a lot has happened which lost in translation due to the film jumping between the past and present all the time. If you really love the franchise and want to know it like a geek, we have a explanation video here that breaks down the first three films in painful detail and the significance of all its dead and undead characters, So here you go horror buffs, enjoy!
