"I'm one with the force and the force is with me" - Chirrut Imwe
You know when you go a fancy, made per order restaurant? You decide what you want and the waiter tells you it'll be approximately an hour before your meal will be served, so you order an appetizer.
You have a couple glasses of merlot and eat your way through the garlic bread. As you continue to wait for your main course you think albeit the garlic bread was delicious, it's not what you came for. You're satisfied but still wanting.
That's exactly how I felt after watching Rogue One. It was good and it'll do until the next one, but it wasn't what I came for.
