Gridman was one of my favourite anime from 2018. I say this despite not being into Tokusatsu all that much. The way Gridman challenged your expectations and left you with grand anticipation for every new episode, plus the excellent contrast between the human/existential drama and the over-the-top action made it one of my favourites. Dynazenon on the other hand, is thoroughly average all the way through.
For what it is, Dynazenon is still a fine and competent show, but it's really missing that extra something to really reel you into its world. The human drama and high stakes action are still there, though less intense compared to its predecessor in both aspects. It's an average tokusatsu that doesn't do enough to elevate itself beyond mediocrity. The music isn't as good, the animation is less refined (though understandable given current conditions), and the action scenes all blend together. The show also reuses its transformation/combination stock animations far too much to the point of just making them unimpressive and dull as the episode rolled on.
The plot itself doesn't go anywhere interesting, with the complete apathy of the general populace to their city being destroyed each episode (apart from like one scene) being such a strange detail I swore it was a plot point (it wasn't). It's your typical coming of age plot, learning to work with others, moving on yadda yadda yadda. The characters are again just fine. Like, there's nothing truly outstanding about this, which wouldn't be such a problem if this were a standalone, but the fact that it had to follow up Gridman leaves a lot to be desired.
As it stands, Dynazenon is thoroughly average. It doesn't do anything particularly bad, nor does it do anything particularly good, though thankfully it isn't boring. But coming of the heels of Gridman, and having director Amamiya at its helm, it's not unfair to have such raised expectations coming into this.
