I can't say that Bloodivores anime is a good example of racism but I can firstly tell base on the plot of the story how the humans hates the vampires on their community. That is my first impression though but not long after I started reading the webcomic online. I thought that the story itself is not worth watching but I was wrong. Yes, the anime's transition is kinda confusing and annoying at the same time but not the original content.
Would the anime adaptation of Space-Time Prisoner gets a second season? Well, to be honest I don't think that it has a lot of support from the anime fans. I don't like the anime adaptation but I don't hate it either. I just wished that it had a better adaptation so that more fans behind the anime screens would understand, love and enjoy watching it. This is my personal opinion though but I wish it gets season two.
