The best new science-fiction shows of 2026

New Year is a time of reinvention. In that spirit, I would like to shake up this preview of 2026's best sci-fi and science-related TV with a radical act: including a series that started last year. That may seem strange, but the second season of Fallout (Amazon Prime Video) aired in only mid-December, so, for my money, it counts. Set in a retrofuturistic US, generations of humans have lived inside radiation-proof bunkers sold to them by the shadowy Vault-Tec corporation. Last season, former vault-dweller Lucy (Ella Purnell) went surface-side to find her missing father, encountering cowboys and cannibals along the way.
