Last year's X-Men: Days of Future Past left the long-running franchise in a particularly exciting place; the weaker entries in the series have been eradicated entirely, and the filmmakers now have two eras to explore in future installments: the present-day storyline starring the original trilogy cast, and the prequel storyline that began with X-Men: First Class. However, despite this new setup, it looks like next year's entry, X-Men: Apocalypse, will spend most (if not all) of its running time in the past.
