This is the best part of Grand Order so far. The other movies are... mediocre at best. The only fate movie triology that is good is Fate Heavens Feel.
I think if they made more series instead, it would've worked better. Or just one big series with multiple seasons.
With that said, to be able to understand this TV series properly you have to watch the original Fate series first, which are
1. Fate/stay night 2. Fate/stay night Unlimited Blade Works 3. Fate/Zero 4. Fate/stay night Heaven's Feel
Then after that to understand how "Grand Order" started and the references in this series:
1. Fate/Grand Order: First Order 2. Absolute Demonic Front: Babylonia - Initium Iter
If you watched all of those, you'll enjoy this series much more.
