I'll keep this as short as I can with Anilist's character requirement in mind, and do my best to avoid plot summaries and spoilers.

If your question is whether or not you think this is a good investment of your time to watch, the answer is overwhelmingly yes. The best way I can describe this show is as a mosaic of intriguing, but somewhat disconnected stories across decades that continuously up the emotional ante and personal investment in [Vivy] the main character's journey, bringing it all crashing down on our hearts in the final scene of the show.

The final scene was particularly powerful to me (so much so I had to watch it twice just to fully absorb what was happening), because I was met with the immediate realization the end is the culmination of every episode before it, and that every episode was a melody in the ultimate song that was this show. Speaking of music, the songs were amazingly performed, and I did understand and feel the subtle distinction between what the show was trying to tell me was "with-heart" vs. being "artificial". This is indeed a show though where you don't skip the OP though, especially considering the animators did put some important story-telling cues in the OP as it does change from time to time.

As for the animation, as the headline suggests, it is also a major component of the effective storytelling at work here. Wit once again beautifully balances their elegant and detailed stills that tug at your heartstrings with rhythmic and flowing fight choreography that really reminds you why they were the original animators for AOT. It's rare I see fights as detailed and even realistic as this that don't rely on slow-mo or impact frames (both of which are fine, my point being the animation here shines without that makeup). Whether slow or fast, the eye candy here is truly up to the task of breathing life into this story about robots.

All that praise being said, it's not to say this show was without faults. The time jumps could be a bit jarring, and a couple of times there was important information in an after-credits scene I missed. The beginning does take a hot second to get off the ground, but I think Vivy is an endearing enough character to carry easily until the plot picks up. There are a couple of loose ends left untouched, although I might argue they are not that important, and even a couple I thought were going to be left in the dust did manage to make it back in time for the final matinee. But the main resolution and plot left me very satisfied as a viewer.

In a weird way, I'd compare this story structure to Doctor Who. An immortal and his companion on an anthological journey that culminates at the end of the season, exploring personal philosophy along the way. All in all, I'd recommend tagging along with them for the 13-episode adventure, I severely doubt you'll regret it.
