Unfortunately the scenes set in the real world (the locations include Camden Lock and the London Zoo) are stilted and unconvincing, while those in the chatrooms become increasingly tedious.

Pantomimic dialogue, stagey sets and underwritten characters render this instantly obsolescent.

Director Hideo "The Ring" Nakata never connects with the script (by Enda Walsh, adapting from his own play).

Veers into thriller territory with predictable results. It's strange that a movie so lacking in substance arrives with such pedigree.
