I fell asleep somewhere in the middle for about 20 minutes, so I'm a little more confused than the typical first view would probably leave me. I'm most confused about Dodd (as in I know nothing about him--his death is probably where I was napping) and Natalie's boyfriend who Leonard kills for some reason, and then puts on his suit for another reason.
Also, is it completely confirmed that Teddy is the one who did it, or am I supposed to be wondering if he was telling the truth at the end (beginning?) of the movie?
I could tell it was a good movie, and I'll probably watch it again sometime. I was hoping somebody could help make the story more clear to me so that I can have all those "ah hah" moments on my next watch.
