I was excited to see Lee Si Eon finally take the lead role but unfortunately his promising acting skills couldn't cover up the horrid script-writing. "Killed My Wife" was slow-paced, boring and overall mediocre. Worst of all, the ending made me regret starting the movie. It was as if the writer couldn't be bothered to finish the script so they just threw in whatever idea they had into the ending scene. I wouldn't recommend this to anyone. If you're looking for a much better film with a similar concept, I highly suggest watching "The Vanished" instead
