An anticlimax resolution for a story is a poor or too simple resolution for a story that otherwise would be pretty exciting and you´d expect it to end ina very awesome way, an example of an anticlimax resolution that didn´t paid off was the resolution in Batman vs Superman where the whole conflict was solved when superman says Martha, as is his mother´s name and it turns out that was Batman´s Mother´s name as well. So it could leave the audience unsatisfied, that´s could be damaging the story.
An anticlimax is a disappointing (or unsatifying) ending to an otherwise exciting series of events. Example: think of an action movie that just ends without wrapping up the loose ends or leaves too many unanswered questions.
