I love this anime movie I think it is better than the other My Hero movies, as it is among my absolute favorites in terms of execution. This unique story of a good calibre tells a interesting tale at an amazing pace. The art to me is personally is as great as this type of anime could be, however that could be Bias. The characters are well-rounded and have many flaws and strengths, although any part that focuses on the more minor characters is slightly worse than the main story. The characters are very relatable and grew well in their development, which is quite a featin these highly unusual scenarios. The world ending cataclysm was quite intriguing as it has many parallels to real life history. The villainy had good powers but could have been more in-depth in his backstory and reasoning.
I feel anyone with good taste will enjoy this anime and all it has to offer to the world at large, including non-anime watchers. I will probably like to re-watch this work in the future, because it has an amazing level of re-watch-ability as I have watched it several times already.

It's earned it's place in my heart as I hope it will yours' as well. I whole-heartily recommend it to all.
