Atlanta has always felt snubbed by hostility from the IOC, who didn't like the level of private corporate sponsorship used to fund the 1996 Games (nevermind that two decades later, it would be considered modestly quaint today).

However, it was overwhelmingly a successful Games. It created a lasted economic boom, and much of the construction saw continued use or was repurposed afterward.

Today, Atlanta is not really remembered as a "bad" Olympics (because international sports organizatinos like the IOC and FIFA have become more disgustingly capitalistic than we ever were). We are likewise not really remembered as an "success" story either, frankly because most cultural commentary prefers not to think about southern American cities at all outside the context of sweeping generalizations about racism (1). But quietly, it was an example of a success story for the host city.

(1) Yeah, between the '96 Games and this year's Super Bowl, Atlanta sports fans are a pretty bitter crowd. Don't mind us!
