Full Metal Panic! Season 4

2018 12 Episodes Animation · Sci-Fi & Fantasy ⭐ 7/10

Full Metal Panic! Season 4 has built a real following on and among viewers who want their sci-fi to think as hard as it looks. The 1-season run is exactly the right length for what it is doing. 142 viewers have already rated it on TMDB — the kind of consensus that does not happen by accident. Tomokazu Seki sets the tone, and the world-building does the rest. Available now — press play and find out why people keep recommending it.

Part of the current wave of titles people are actually watching, Full Metal Panic! Season 4 earns its spot. What makes Full Metal Panic! Season 4 work is that the ideas never crowd out the people having them. Amalgam has made its move to gather up the whispered—specifically Kaname Chidori! And Leonard Testarossa is ready to do anything to get her. Determined to keep Chidori safe, Sousuke stays close by her side, which proves to be more dangerous than ever before. Tomokazu Seki and Satsuki Yukino lead a cast that brings real weight to the material. It was aired in 2018. What separates Full Metal Panic! Season 4 from lesser genre entertainment is a willingness to let the concept cost the characters something. There is real craft here, even in the moments that do not fully land.

Full Metal Panic! Season 4 is satisfying on multiple levels — something to watch and something to think about after. It stands on its own even without an obvious comparison point. A contained run means every episode is doing real work. Tomokazu Seki grounds the bigger ideas in something human. Once you are in, you will want to talk about it.
