Just watched it.
Some spoilers ahead.
[The story sucks, most harem anime would have a better story that this. They never explained why England is killing all the immigrants. If you don’t have new babies being born, wouldn’t you want to keep people in your country? And there was no explanation to why this woman can get pregnant, nothing. Was it cuz she’s a prostitute and got fucked a lot? lol. ]But man, the battle scenes are so nice, it’s like watching a live action CS when the England army and the Fish terrorists fight. The camera angle is very well done. Like usually they just use shaky camera, but this is not, it’s like watching other players play cs in third person view after you’re dead. That was cool. They should’ve make this a fps, not a movie. As a movie, I give it 5/10.
