I think the fatigue is a product of the fact they have no heart or feeling

irony is fun and all but ultimately people want sincerity. Irony and wit are like icing people like them but there has to be something more substantial there or you just walk away feeling unsatisfied and slightly sick

Terry Pratchett's work is a good example of how this can work he's very ironic and uses a lot of witicisms but underneath it all there is a clear depth of feeling and the books are also full of profound and sincere statements and moments
