Both entities arrive without invitation and leave without explanation. Beyond this, the Poltergeist and the Banshee have remarkably little in common, which makes the present comparison both instructive and, from a methodological standpoint, faintly absurd.
The Poltergeist operates globally, with no apparent agenda beyond inconvenience. The Banshee operates regionally, with a single, precisely defined agenda it executes with considerable professionalism. Comparing them is a little like comparing a fox in a kitchen to a scheduled train service — one is chaos, the other is a timetable, and both will ruin your evening.
