The Opening was exactly what I expected.
Focus mainly on the OG starters of Ash: Bulbasaur, Squirtle and Charizard. + Obviously Pikachu
Focus mainly on OG Trio: Ash, Misty and Brock
Focus mainly on OG Scenes: Ash's gym battles, the snowstorm episode (One of the best), Hollywood Episode
Others got a collage picture, but that was the right way. To become full circle, you have to take that route.
It started with them, it will end with them.
Just wished, that they rotated his pokemon team like this in Journeys as well. All fans would be happy.
