This is not Del Toro’s best. In fact, it is not a very good film in general. Del Toro made a way too Hollywood Victorian ghost house horror film with a very unsurprising story and yawn inspiring special effects.
The American Edith falls in love with the English Thomas who takes her to his gigantic mansion where he lives with his sister. Edith already saw ghosts and of course Thomas’ house is haunted, so Edith tries to get away.
It is not that the film is extremely boring or badly made, but it is but a Hollywood horror production with a very thin Del Toro varnish in fantasy atmosphere.
