20) Insidious 

When their son Dalton falls into a coma after witnessing something in the family attic, married couple Josh and Renai begin to notice horrific supernatural phenomena. Believing the house is haunted, they move away in search of a fresh start. But the presence has followed them here, too. Soon, Josh and Renai discover that Dalton is the key to these occurrences - and that he is in no ordinary coma…

Insidious is something of a throwback, using tropes of demonology and spiritualism that are almost dated in today’s increasingly secular entertainment circles. But James Wan’s taut direction and a keen sense of atmosphere make this old-school haunted-house story feel fresh.
