The great thing about “Wall Street” (1987) is you can enjoy it no matter which side you are on in the whole “greed vs. socialism” thing. You can tsk, tsk about the overindulgences of corporate raiders like Gordon Gekko, and feel satisfied when the union boss’ son (Charlie Sheen) learns his lesson in the end. But there’s a reason Michael Douglas won an Oscar playing Gekko. He does one hell of a sales job explaining why “greed is good.” If Gekko had played Darth Vader (his closest movie counterpart), you might have been cheering for him instead of Luke Skywalker.
