The movie The Host was a surprisingly enjoyable story of alien invasion, sort of Heinlein’s Puppet Masters redone as a fem-centric YA story with an ending based on collaboration rather than conquest. Which makes sense, since it is also a romance, but much better done than the authors other movie series with all the sparkly vampires.
In Anime, Blue Exorcist: Complete 1st Season is the ultimate in inter-generational infighting; Th son is becoming a world-class exorcist going after demons. The father is Satan, infiltrating his minions into the world of humans. Gyo: Tokyo Fish Attack! is more scientific, with mechanically augmented sea creatures attacking the land dwellers. Our protagonist leaves Okinawa and heads to Tokyo to see if her boyfriend is OK, only to discover the city overrun by the mechanized monsters.
