It's a Godzilla series. I liked the cast and enjoyed the first episode, but even so... Godzilla. I don't hate kaijuu, but their stories are inherently boring unless you do something to subvert the formula. Mindless monster wanders around. Soldiers shoot at it. Repeat. Why do people think this is interesting? I genuinely don't get it. There's no human element in that loop at all. (The soldiers are usually humans, yes, but human drama involves characters making character-based choices. Lots of soldiers shooting at kaijuu are liable to be, on that level, indistinguishable between groups of ants fighting.)

Clever scientists are doing Clever Scientist things. This is also traditional, but this series goes nuts with quantum physics, time-bending and, unfortunately, some bullshit that means the show is a lot less clever than it thinks it is.

Ep.3: "Everything that happens in the future is predetermined." No, sorry, come off it. Chaos theory, fractals, butterfly effect, etc. Causal determinism and Laplace's demon (in the real universe, at any rate) are dead and buried, but this misconception still pops up from time to time in anime.

Ep.5: on seeing a kaijuu that can bounce your bullets back at you, our genius hero infers that it can see the future and use this information to angle its back armour in order to repel your bullets. Instead of, uh, being bulletproof. He doesn't consider the latter possibility. (His assumption is right, but that doesn't change the fact that his logic processes are from Planet Mushbrain.)

There are two geniuses and lots of super-clever scientists. One genius is Yun Arikawa (male), who creates sentient AIs with fairly tiresome personality options. The other is Mei Kamino (female), whose university subject is a cross between quantum mechanics and mythology. That's about to become more useful than it would ever be in the real world. She's likeable, but she's stuck in a Scientists Talk Science B-plot that's full of high-level technobabble and is ultimately just a geekier version of that "soldiers attack kaijuu" plot role. (That's still better than any scene with actual kaijuu, though.)

Apparently, Godzilla fans were excited by this series's choice of kaijuu. Instead of relying on the big five as usual (Godzilla, Radon/Rodan, Mechagodzilla, Mothra and King Ghidorah), the show resurrects some comparatively neglected ones and even invents some more. Also, the music is very Godzilla and pretty cool.

I don't hate this show. It has charm and even (in ep.6) a curious, playful kaijuu. (Was there any need to kill it?) It's not bad, until it turns into a Godzilla series and... oh dear. If you're me. But there are lots of Godzilla fans out there, so by all means listen to them instead.
