I'd rate this a decent film on it's own merits but it's influence on subsequent stock broker-y type films can't be ignored.
From direct reference in Boiler Room, to the levels of extravagance be imitated in pretty much every film of the genre (sub-genre?) this is not to be sniffed at.
Never really rated Charlie Sheen acting wise and I'd put this forward as another example. Some other good performances of course, Douglas obviously and Sheen Snr in particular.
