People seem to miss the memo for this show. They think its only a show about fighting with the power of song. But if they think that, they miss the full story. It is about showing humanity can pull through together, even in the worst odds, as long as the intention is positive and true. It's not meaningless combat. SI-VIS does go overboard with character tropes as some of the reviews have pointed out. But, they did resolve themselves over time. If you can pull through the rather excessive character trope slop of the early episodes, you get properly rewarded with the show re-railing itself. Itgets back up on its feet, reducing the impact of some character tropes. It changes focus and corrects its direction and pacing around the midway point. Towards the end of the series past EP 17, SI-VIS truly shows its colors and the writing solidifies itself.

While saying that, I believe they had designed and written the series to be two 12/13 episode seasons; but they ended up getting a full 24 episode season in one shot. It may explain why some of it seems rushed in the first half, and yet can help explain the change in tone and pacing found past that EP 12/13 point.

It's worth noting that even with the series rough starting episodes and first half, It does properly entertain along the way and even then with its highly predictable dramatized tropes manage to break what you expect the character or show to do. It manages to include quite a few subversions of expectations that later prove to define the characters growth over the series, all without making the show seem like it lost its direction or had a rewrite midway. It also lacks any filler episodes. No episode lacked plot or purpose.

The characters are properly enjoyable, mostly stay on theme, and are relatable. It brings real but heavy topics to the table, and handles them all excellently. Its a love letter to hope in humanity on par with Superman... Well, If Superman was an Idol group. The show properly covers having a Gray Antagonist faction and characters. The conflict is not the one you first expect it to be. Everything, even the villains, stems from misbelief, and grief; which the show properly covers and shows that you can work through issues. Even if they regress, the show characters must pick themselves back up. And they do, excellently.

Animation remains consistent throughout, and the audio design is unbeatable. Songs strike powerful emotion when needed. Characters gradually lose their comedic/dramatized tropes and grow out of their first impressions shell. The finale episode is proper, fulfilling and is left open ended for headcanons and fanon interpretation; as well as potentially gain a second season/series. It also properly sets up the series to be a multimedia concert franchise like how Symphogear or Uma-Musume is.

Overall, SI-VIS has a more proper lead up to a more deserved and rewarding finale than most other series I've seen this 2026 Winter release. It's able to wrap in the viewer with lessons of hopecore and yet admits that in despair you can be blinded to the chance in front of you.
