If you seriously must know an example, It's a Wonderful Life is now considered a Christmas classic, but wasn't so at the time of its release. In a similar vein, A Christmas Story only had moderate success at the time of its release.
According to Rotten Tomatoes, Blade Runner was "Misunderstood when it first hit theaters."
Though, I think these films would constitute more as "underappreciated" rather than completely negative.
Standard definition of "cult-classic" is what I'm guessing he's going at.
I suppose you could consider that too.
