As much as I like this movie, I have to point out one very serious and glaring issue with it: how can Leonard know he has a condition if he can’t make new memories? I saw a documentary show about a composer that got herpes that spread up into his brain and gave him a fever so bad that it fried it and he has the actual condition were he can’t make new memories. He acts like Geoffrey Rush in “Shine” (which is funny because he’s a musician) and he’s really spastic and crazy. He has no idea his kids are grown up and that his wife has divorced him and remarried. When she visits him, he thinks they’re still married. He has no idea he has a condition because he can’t remember it. Leonard shouldn’t be able to know that he can’t make new memories because he would’ve learned about that after the attack.
