Best for: Strong choice for describing shallow social situations or empty creative work.

So dull that it induces drowsiness or sleep in those exposed to it.

Best for: Rare and literary; best deployed in written criticism where you want to sound quietly devastating.

Stuffily dull and airless in atmosphere, evoking musty stagnation.
