Example of no-budget movie success - but what is success?

News report about Marc Price who has had a no-budget success with a zombie movie.  Good advice on how to make a no-budget movie - quality of acting performance matters more than the camera.  Questions - is this yet another zombie movie or are there elements of originality or allegorical themes to this?  Anyone know of recognition for no-budget movies with in depth themes like social justice?  I am aiming to start a no-budget movie project going with risk-taking originality - and to me it is essential to do that to make the time worthwhile.
