Watch My Bloody Valentine

In the small town of Harmony, a tragedy occurred on Valentine's Day ten years ago. A miner named Harry Warden went on a killing spree after he was trapped inside the mine and had to resort to cannibalism to survive. The townspeople believed Harry to be dead but the murders stop once he is presumed dead. Ten years later, the town is preparing for Valentine's Day festivities and is also reopening the mine after being closed for a decade. Tom Hanniger (Jensen Ackles) returns to his hometown after 10 years of being away. He was the one who caused the accident which led to Harry's killing spree and the deaths of several other miners. His return to town is met with mixed emotions from the town folk who still haven't forgotten his past. Tom is trying to make amends for his past mistakes, but everyone in town seems to remember the tragic events of that Valentine's Day and the role he played in them.

Shortly after his arrival, people in the town begin to be killed one by one by a figure wearing a miner's suit, proving that Harry Warden might still be alive. The killings coincide with Tom's return, and he becomes the prime suspect. Tom, aided by his former girlfriend, Sarah (Jaime King), tries to clear his name and uncover the truth behind the murders. The mayor, played by Kerr Smith, is determined to carry on with the festivities despite the murders happening in the town.

The film is a remake of the 1981 Canadian slasher film of the same name, which was known for its graphic violence and use of 3D effects. The 2009 version, directed by Patrick Lussier, also utilizes 3D technology to increase the fear factor. The film features bloody and gory sequences that keep the audience on the edge of their seats. The film's setting in a dark, eerie mining town adds to the creepy atmosphere.

The performances in the film are decent. Jensen Ackles portrays Tom Hanniger as a sympathetic but flawed character. He tries to redeem himself for his past actions but is met with resistance from some members of the town who have not forgiven him. Jaime King plays Sarah Palmer, Tom's former girlfriend who still has feelings for him. She is also trying to protect him from being the next victim. Kerr Smith, known for his role in the TV series 'Dawson’s Creek,' is the town's stubborn and pompous mayor who insists on carrying on with the Valentine's Day festivities despite the danger.

The film also features a killer in a miner suit that is terrifying and adds to the horror atmosphere. The suit is menacing and ominous, and it makes the killer all the more frightening. The films' ending is surprising and leaves the audience in awe of what they've just witnessed.

Overall, My Bloody Valentine is a slasher horror film that keeps you on the edge of your seat. It is a decent remake of the original 1981 Canadian film and has successfully used 3D technology to create a visually stunning horror experience.
