No, this is not the thriller about man eating sharks. Yes, this is an incredibly boring drama in the vein of most Merchant Ivory films. The film stars Rachel Weisz as Hester, who is married to a man significantly older than her and decides to cheat on him with Freddy (Tom Hiddleston.) You know where this is going.
The main problem with the film is that it's so predictable that it quickly becomes uninteresting. The acting is wooden, the story elementary and basic, and the direction so bleak that it takes away from the movie's few interesting moments. There is nothing to like here except for two or three scenes that come off as slightly realistic, and therefore are more interesting than the rest of the film.
We don't like Hester. Perhaps that's the point, but if it is..it's a weak and lazy point. We don't like Freddy...same thing. These characters go through emotional roller coasters and crises, but they are happy people, and we are not happy about this. I won't tell you whether or not they are happy in the end, but they are happy during the film.
The Deep Blue Sea is a bad film, but it's also a respectable one. It tries to raise issues that happen in real life, but just doesn't get there. I will acknowledge why some people will like this film. However, if you have seen a Merchant Ivory film and have been mercilessly bored to tears by it (as I have) then just skip this one.
(1 and 1/2 Stars out of 5, The film is rated R for a scene of sexuality and nudity)
