I'm looking for a word for a difficult situation or process that can seem meaningless at times.
Example: Unlike Beowulf, the Secular movement did not defeat its enemy (Faith) in a glorious battle but through a ____ dialog through the ages.
Meaningless - the subject is not meaningless.
Feudal - feudalism is meaningless.
Trivial - the subject is important/has value and it doesn't express the difficulty of the subject.
