'The Weight of Water' tells two stories simultaneously. It is only Maren's story that keeps the viewer engaged while Jean's story is halfbaked. In spite of having a stellar cast, the latter story required further development. For example, one doesn't understand why Jean feels so connected to the murders that happened more than a hundred year ago. She's so drawn to it that she prefers to give that more focus than her failing marriage. With the exception of Jean, none of the other characters seem defined enough for us to care about. Maren's story ends up dominating the other. It starts off as rather boring but as events unfold, we're further drawn into it. Yet, more importantly, what is the connection between the two stories? That's one crucial point 'The Weight of Water' fails to make. Catherine McCormack does a fine job with a difficult role. However the screenplay, does not allow her to portray the complex feelings her character is experiencing. Sarah Polley too impresses with a complex role. Sean Penn disappoints. He seems rather uninterested most of the time. Elizabeth Hurley is quite alright as a shameless seductress. She does look sizzling but the screenplay doesn't give her much scope to perform. 'The Weight of Water' tries to be an impactive film but it just doesn't work. Only half the film is worth watching.
