7 Pounds, Button

Has anyone seen 7 Pounds or Benjamin Button? Both look somber, somewhat artsy-drama, and different, which means my wife will make sure we see them eventually. But I've yet to talk to hear from anyone I know how either of them are. They certainly both have their star power, with 2 of Hollywood's leading men in lead roles. Benjamin Button is probably the one I'm most curious to see. If you've seen one of them, what is your analysis?
