The Devil Beneath is, in Australian slang, "pretty stink". There's a dose of woke twaddle, I can ignore but the rather tedious story plus the really bad special effects, let this thing down.
Perhaps the only upside, is the acting is mostly alright but so much else is off, well, it makes it hard to say positive things.
In summary, a pretty basic, not terribly good horror, from down under.
