The story? Uhhh, not so much.
I came across this by chance and went in blind-- it is VERY explicit in some parts, and one of the plotlines is centered around incest between siblings. I personally found the sexual aspects of this movie to be pretty uncomfortable, and I can't say they really added to the story for me. Other things of note; weird penile aliens, "tentacle" action, and probably more my brain repressed.
The main attraction for Doomed Megalopolis is its animation, and it's honestly really fun. Some of the character design in DM is a bit cookie-cutter, but movement and the action scenes move well enough. I thought backgrounds were well-done, and even if some characters were similar they all looked good. My favorite part of the animation style though, is how over the top this film gets with its flashing/light/laser beam attacks. It makes the stakes of the plot seem really dire, as if each character is fighting full-throttle the whole time, but also makes things feel a bit ridiculous and silly.
Overall, if you have a strong enough stomach, I'd recommend this for some art inspiration. I really don't think the story is that special (plus it's weird and uncomfortable), but it's obviously reflected in the artwork.
