I've got to admit: I'm not a huge anime fan. In fact for the most part I find it a bit boring. What attracted me to this film was the story- old man get put in a life support machine and it goes crazy and he become a robot ravaging the city. Plus it was done by the same dude as Akira and I love that movie to no end.
The actual movie is actually pretty cool and funny. I would suggest watching it if you want to see something different.
It had slow pacing, much like the Hammer films and other horror flick from the UK, which lead me to believe that it's a thing about british cinema.
Besides that it was interesting enough, and out-there enough to be enjoyed.
It's quite a kooky horror tale.
