Overall I really really enjoyed it.
The story is centred on a very sweet 12,000 year love story
The animation is đź‘Ś
The first 2/3rds or so of the show is very episodic, but that allows for some really interesting and sometimes silly episodes
The finale is an absolute banger
A lot of episodes end with the most ridiculous deus ex machina possible, constantly one-upping the previous ones, but that’s sorta part of the fun? It feels like it’s doing it on purpose almost and it’s very entertaining. It gets to the point where some of the show is just utter nonsense, but I mean that in the best way possible.
The fan service feels kinda gratuitous (why do they almost orgasm whenever the mechs merge) but that’s just an anime thing I guess.
Overall I enjoyed it a lot.
