It's safe to say that Josh Lambert (Patrick Wilson) looks tired in Insidious: The Red Door, and it doesn't come as a shock either; he's been through a lot. After all, by this point in the storyline, his mother has passed, he's divorced and at least one of his children, Dalton (Ty Simpkins), is not his biggest fan. However, Josh isn't the only one who's experienced a lot of emotional turmoil. Specifically, the film's plot emphasizes how everyone in the Lambert family has been through the wringer over the last decade.
