"I viewed this film for the first time last night. It's been out since 09 so it's been around for a while. To be brief I thought it was an interesting movie. A bit tedious on the replays but an important aspect to show the length of the cycle she was trapped in. i agree with the symbolic reference to the mythological storyline but it probably goes much deeper than that. I will delve into that question in another post but for now I have not seen reference to the number 237. Coincidental that the room # on the ship where much transpired and the address number of the house was 237. May possibly been in the number on the boat and other places. I will have to watch again to be sure. I would guess there is some symbolism to it's recurrence in the movie and may open another tangent for the storyline."
