Not Game of Thrones — but Even Better: The Perfect Fantasy Alternative to the HBO Hit, with Just Three Seasons and an Impressive Rating
And it’s hard to imagine any viewer calling the finale a disgrace.
While HBO continues to chase the shadow of Game of Thrones with House of the Dragon, MGM+ has quietly offered a compelling alternative for the past four years — Britannia. This historical fantasy drama charts Rome’s invasion of Britain, where Druids, Celts, and a formidable heroine, played by Kelly Reilly, resist the empire’s advance. Yes, the very same Kelly Reilly known for Yellowstone, now wielding sword and prophecy.
With only three seasons under its belt, Britannia has earned an impressive 92% rating. This acclaim isn’t for lavish effects or dragons, but for its strikingly original and audacious storytelling. Far from being a mere Game of Thrones clone, Britannia offers psychedelic magic, chaotic politics, and family intrigues that defy convention.
Reviewers at FandomWire insist this series is "not Game of Thrones, but something even better."
Created by the Butterworth brothers, the show eschews typical fantasy tropes — no destined heroes or standard quests here. Instead, it immerses viewers in pagan rituals, mysterious gods, and Kelly Reilly’s magnetic performance as Princess Kerra.
She is a sharp, politically weary woman caught between ancient traditions and the looming Roman conquest, portrayed with both ruthlessness and vulnerability — a refreshing depth in a genre that often sidelines female characters.
Though Britannia remains a niche favourite rather than mainstream, for those fatigued by endless Game of Thrones imitators, it offers a wild, strange, and utterly compelling watch.
