The ending is preposterously shoddy, typical of a film that is mostly, yes, agony.

It's a shame that, for all of its unnerving tonal registers, not to mention a gorgeous score, Agony winds up with a painfully predictable ending.

Unfortunately, titling a film Agony invites facetious comments about what it feels like to have to watch it.

Michele Civetta's début has all the elements of the Gothic in their proper places, with a hint of giallo, but there is simply no narrative glue to hold them together.
