Query: Fair overview with terrible narration

This is a one-hour documentary about US Navy carriers since their inception after World War 1. It covers most of the important historical aspects of carrier aviation in the US Navy, and if you aren't very familiar with our Navy it is a fair overview to start with. The narration, however, is awful. Why produce a documentary like this and not bother to get a professional voice-over? It seriously hurts the effort overall.
