Right now you can watch Theodosia in Australia on Amazon Prime Video, and in the US on BYUtv — and it goes further with its ideas than most genre entertainment bothers to. 2 seasons in, and the quality has not slipped. 19 people have weighed in on TMDB, and the verdict leans heavily positive. Eloise Little sets the tone, and the world-building does the rest. There is no real reason to keep putting it off — it is right there on Amazon Prime Video.

There is a reason Theodosia keeps coming up in conversation. What makes Theodosia work is that the ideas never crowd out the people having them. In 1906 London, 14-year-old Theodosia “Theo” Throckmorton gathers an eclectic team that includes her younger brother Henry, along with friends Will and Egyptian Princess, Safiya, to fight a powerful secret society bent on destroying the world with ancient Egyptian dark magic. The human element stays intact thanks to Eloise Little and Nana Agyeman-Bediako, who anchor every scene. Across 2 seasons (2022–2024), it never lost the thread that made it worth starting. Theodosia resists the temptation to explain everything, trusting the audience to sit with ambiguity. The hit rate here is high enough that skipping ahead never feels like an option.

Viewers burned by ambitious sci-fi that could not sustain its premise should give Theodosia a chance. The tonal similarities to Moon Knight are real, though Theodosia carves out its own identity quickly. A contained run means every episode is doing real work. Eloise Little anchors it with a performance that makes the more abstract moments feel personal. If you have been burned by ambitious sci-fi before, this is the exception.

Theodosia wrapped up in 2024 — and 2 seasons are available to watch from start to finish.
