But shouldn't it be interpreted as negative? It blew up.
The fact they made it so much further than the first launch, seemingly having corrected all the notable things that went wrong there, is very good news - the flight test process serves to root out unknowns and today's launch shows they've done so (and now found some more to work on for the next launch).
So to answer your question, I don't think it should really be interpreted as a negative, as the primary goals were met and the controlled nature of the launch seems promising for SpaceX getting cleared to keep trying.
First launch had something analogous to latter, this launch had two counts analogous to the former.
Safety is always more important than getting your rocket to orbit.
They fixed previous mistakes and made new ones. Eventually if they don't repeat the same ones they will run out of big mistakes and it will be smooth sailing afterwards.
