I haven't watched this yet, I'm still trying to get through all of the December movies that I haven't seen yet 😑
The timeline you posted is really helpful because I'll admit, I only saw the first Insidious movie lol...do you think I need to see the second and third to understand the fourth?
Thanks! You can watch it all and skip Insidious : Last Key . That will be sufficient enough. This sequel seems to be forced to fit in...
