I thought some moments were cringe like whenever they grunted when attacking. 002 is basically unstoppable which made fighting scenes boring. The story was a bit rushed, like all of a sudden out of nowhere with no build up, there is a giant OP klaxasaur that 002 and hiro operate. All of a sudden klaxasaurs are the good guys? It happened in the span of 2 minutes, like what is the writer thinking? Ok and explain to me how they were able to destroy the entirety of Virm in a single episode. Virm was also really rushed, like out of nowhere two guys with masks turn out to be ghosts that have tried to take over the world for 60million years? This anime had some serious potential with good voice acting and animations, but there was a lack of struggle during battle with an overly rushed plot.
Everyone says this anime is sad, but I don't think its that sad. I would have liked to see hiro and 002 alive so they can continue their well built relationship, but they died. To me this is upsetting because it feels like a waste of character development. Even so, nothing about this anime was really sad.
