If you have yet to watch any of the Heaven’s Feel movies, we recommend watching the Fate/Stay Night: Unlimited Blade Works anime series first (the one by ufotable, not by Studio DEEN). The aforementioned series is based on the second route of the Fate/Stay Night visual novel, and is a much better starting point to the wider Fate series compared to the Heaven’s Feel movies.
