Why This?

Akira came into the anime industry in 1988. But don’t underestimate it just because its animation is from the quality of the 1990s. Its animation is quite good compared to the anime, even in around the 2000s.

The intense action scenes, thrilling plot, and epic background music are the aspects that made it a masterpiece movie of the 1990s. So, if you want to watch a sci-fi anime with action as the main base, then Akira is the one you’re looking for.
