Memento

At first this movie confused me, but as it ran its course I became more and more intrigued trying to figure out what was actually going on. I liked Leonard in the beginning, but after the plot twist was revealed I had a harder time sympathizing with him because of what he decided to do. He lost the meaning of what he was doing, and he used his condition to continue killing John G.'s even though he had already gotten the one who hard attacked his wife. The only thing he had to live for was this act of revenge, and even though Teddy informed him of what he had already done, he chose to ignore it so he could still have a reason to live.
