Knocking on Death's Door (1999) – Mitch Marcus.

Newly wedded paranormal investigators Brad (Brian Bloom), and Danielle (Kimberly Rowe) are tasked by sleazy boss Professor Ballard (John Doe) to document anomalous activities in an isolated, notoriously haunted property. More than their marriage is threatened by the vengeful spirit of the murdered boy Samuel (Brian Glanney) in atmospheric 90s DTV supernatural chiller Knocking on Death's Door. Following a grisly-ghostly incident at the doom-laden domicile, fright fans are magically transported through the ubiquitous '20 Years Later' portal into a shuddersome series of mostly compelling haunted house shenanigans. While this Roger Corman'd creaky-creeper is formulaic, it is well made, with sympathetic protagonists, a winningly creepy location, and a suitably spirited climax. Needless to say when David Carradine's ambivalent character drily intones that 'he doesn't believe in ghosts!', you can be darn tootin', that pretty soon some mightily chagrined spectral entity is gonna royally rip him a new one! Knocking on Death's Door should provide Haunted house fans with an engaging murder mystery, eerie, smokily candle-lit ghost hunting, an ominous, Shining-esque score, plus the beautifully bucolic Irish setting has its very own inimitable charm!
