Just putting it out there, motion comics seem to be embraced by a new younger audience, the older traditional comic book readers tend to not really accept the medium as... well a 'comic'.
I think both have their place and purpose. Its still a matter of time for motion comics to become a main stream form of art and story telling. But I think its the perfect hybrid between print and full animation.
I'd like to think the future of motion comics as a way of telling all those film screenplays and ideas that are way too expensive to make.
While big films require big budgets with big directors and big stars, big ideas can have a life with a smaller budget.
At the moment Motion Comics is open form of art and communication, eventually the consumer will gavitate towards a format that will benchmark the standard.
I think motion comics will come into their own its just a matter of how content creators deliver their stories.
And just like comics their will be great ones and not so great ones.
But it will come down to story, a great story will thrive in any medium.
