At the end of the day, Guyver DOESN'T deliver. that is the main problem and is why many people lose interest.
I've been following Guyver since I was twelve years old and it is still not finished. not because it's massive and epic, but because the mangaka is SLOW and releases such a SMALL amount of material. I won't hear excuses for him any more. he even has an assistant. Ever month when it comes to Guyver release, I am disappointed. it is a total let down. we are being drip fed this manga and it is just depleting all the impact it might otherwise have.
I am seriously considering just releasing the monthly chapter to the pre-orders and not even reading it myself because I want some damn substance.
This is why Guyver is not popular. any time anyone sees Guyver they see a story that is not finished and doesn't look like it'll be finished in any decent pace. They see it has taken almost 30 years to release an amount of story that would fit in a series of 52 episodes. and it's not finished.
I like that Guyver is not finished for the sole reason that I can continue to provide for you guys with this website. it is a big part of my life and I would miss it if it were not here. But it is so damn frustrating that Guyver is really so very unsatisfying.
Guyver is a great story, I love it more than most other stories. But let me ask you about another great story, Harry potter. how would you feel if you could only read a page per week? Would it have been a global success? no of course not. it would have bombed.
