Actually, they do not have to be that way.
There is no need to gush over the elements of the liturgy, either. Its noble structure, language, and ritual are already there in its individual elements. Their truth and goodness are evident to anyone who examines them. When the Word and the ritual come together on a Sunday morning, then they are resurrected to the glory of God. The real beauty of the liturgy lies not in the rubrics or the musical notation. It exists only when the liturgy is being done. In this way, liturgy is like music, which only exists when it is being done, not when it is simply ink on paper.
Liturgical affect, IMO, is the restrained joy of the rubrical workmanship and the spiritual preparation of the worshippers, all brought together in the liturgy (Gk.: "work of the people") by the actual doing thereof.
