Sequels often don't make the same kind of coin as their predecessors.

So the fact that “Neighbors 2: Sorority Rising” couldn’t equal what “Neighbors” earned two years ago in its opening weekend isn’t news.

The new film’s calamitous drop is, though.

The sequel’s $21 million weekend haul represents a 55 percent decrease from the original’s $49 million opening frame.

To quote the late, great Myron Cope, “what a debacle!”

It could be that a sequel to the bawdy but sweet original didn’t make sense. Or, that the new film’s over-the-top liberalism snuffed out most of the laughs.

Either way, a third “Neighbors” is something Seth Rogen and co. will have to put behind the back burner.
