The next Alien needs to avoid a big error that the most recent Predator movie fell victim to. Alien and Predator are two classic sci-fi franchises about extraterrestrial creatures stalking human prey. In terms of both box-office and critical reception, Alien has always stood above its rival. That said, they've both faced the same issue with latter-day sequels. Ridley Scott's prequel duology Prometheus and Alien: Covenant were divisive outings that attempted to rewrite franchise lore, with the latter failing to spawn a planned third installment.
