Sadly some of the punk bands about aren`t that good, are pretty much as described, whereas some are truly amazing, really tight and all able to play very well. I think your standards @Rexel Matadorare the right ones, there`s nothing wrong in any of what you say and I don`t think you`re taking it too seriously at all.
Having been on the punk/Oi circuit the bands that can & do play well rise to getting the good gigs pretty quickly, and there are plenty out there, maybe these guys have that potential but need steering/focusing, sometimes that aspect doesn`t need to be done by the lead songwriter.
