THE MARSH is an absolutely typical ghost story about a lonely woman moving into a lonely house that turns out to be haunted by...yada yada. The end result is that it plays out exactly as you'd expect, featuring the few unlucky actors to be caught up in this mess finding themselves at the mercy of various CGI-augmented spirits whose appearance has been crafted in the most ordinary way.
The script is poor and the direction worse, with none of the creative people involved failing to make anything of the premise. It says much that my memory of the film is already fading, at a rapid pace, a mere 24 hours after I watched it. Gabrielle Anwar (THE TUDORS) fails to bring life to a rather stiff and uninteresting lead character and seems to be trying to get her American accent right rather than delivering a decent performance. Forest Whitaker (PHONE BOOTH) appears slightly befuddled and is probably wondering what he's doing caught up in this nonsense.
Because this is nonsense, I'll make no bones about it. Every haunted house cliché in the book is played out, from the restless ghost of a kid (a little blonde girl, of course) to the vengeful spirit with the scary eyes. The jump scenes are predictable as is the rest of the plot and the effects are poor, taking you out of the movie every time they pop up. A dismal effort, this.
