If you'd phrased it as
The spoiler you gave in Armageddon
...instead of
The spoiler you gave in Armageddon
then it would have been fine, but because you hid the name of the film you were spoiling in the spoiler tags then the necessary context that people need to decide whether to look at the spoilers or not is missing. The only other context you've given prior to posting the spoiler is that the spoilers relates to an "old ass movie" which not only is too vague to provide adequate cover anyway, is also pretty misleading because I don't think anyone would reasonably class a movie from 1998 as "old ass".
