I meant at the end; the ending is the big thing everyone's all goin' on about. If the top does or doesn't fall. It's confusing to me 'cause when he first spins it it looks like its about to fall over, then when we go back to it its upright again. The top was Mal's(official spelling from the credits) totem; if it doesn't then the end, at least, is Mal's dream. Meaning somehow she's alive or something, so forgetting the whole part where he spun a top earlier, the dream he was in at the end would have Mal as the architect. Which, as I said, opens up a myriad of questions. Or brings into quesiton the entire movie.
