Elise Rainier returns to her childhood home to face her fears. The fourth in the Insidious franchise is a prequel which loops back to part one. For series fans only, but well-enough handled in its jumpscares and creepy moments, plus one great idea, decently handled.
A centenary cruise commemorating the first voyage of a new Titanic suffers a similar fate. Typically tatty mockbuster from The Asylum featuring inadequate CG, a slumming character actor (hi, Bruce Davison), and a variable approach to science. Not even fun if watched as camp.
