Never watched any tokusatsu stuff before but decided to give it a try since Chiaka J. Konaka (Serial Experiments Lain, The Big O, Hellsing etc.) worked on it. So I ended up binging
the first 10 episodes which are on YT.
It was quite enjoyable, some of the monsters had really creative designs, ranging from regular Godzilla-likes through some more Cthulhian entitities to rahter abstract beings, such as a giant eye: https://www.youtube.com/watch?v=xvYlu1AQPeo
It might seem like a silly show, but there's easily room for some deeper analysis with regards to the themes of ecology, globalisation, the role of technology/science etc.
BTW only now I realize how much Anno referenced all this stuff in NGE. Well, this particular series came out later, but I suppose the tropes were already established for quite a while.
