My spidey sense is all the manga that is getting cranked out and praised like mad is going to eventually birth the next generation of sci-fi TV and films.
I have to admit, I was a HUGE fan of American anthology comics like "Weird Tales" and "Strange Tales" growing up. My uncle had a massive collection and I just happened to stumble into them and got lost in their pages. A lot of the manga plots remind me of those books. Something like Death Note seems like an episode of the Twilight Zone turned into a series.
Its still very fringe and feels like it could explode in the next 10 to 15 years.
