I definitely had the Enterprise/Faith of the Heart intro as the most discordant and off-putting combination I’ve been subjected too…
Until I started trying to watch Britannia. You’d be watching ancient Roman soldiers talking or swording it out with Celtic Britons and scarified druids against backdrops of mud daubed huts, thick untouched forests, primitive villages etc, and suddenly…you’d be hearing this upbeat folksy 1960s Beatles-like The Hurdy Gurdy Man.
And then you’d go straight back to the ancient Roman soldiers, druids, swords and Celtic style clothing and background.
