If you loved Megazone 23 III - Part 1 - The Awakening of Eve, try Evangelion: Another Impact (Confidential)
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.

Megazone 23 III - Part 1 - The Awakening of Eve

Evangelion: Another Impact (Confidential)
What they share
Both films are directed by Shinji Aramaki, and they both carry the neon soaked mood tag, and they sit in Animation / Science Fiction territory. If that's the register that drew you to Megazone 23 III - Part 1 - The Awakening of Eve, the second film will land in a comparable space — through a different lens.
What Evangelion: Another Impact (Confidential) is
You oversee trials of a massive humanoid weapon. Unit Null suddenly activates, beyond control. Its purpose remains unclear. But its destructive capacity does not. Aramaki's direction evokes anime of the late 80s. The film leaves one wondering about the ethics of technological ambition.
