For myself, I'd feel like a test flight was a full success if it was able to test all the important bits. From that perspective not testing stage separation, second stage ignition, and reentry makes this a partial success but a partial failure as well.

EDIT: Perhaps a better way to think about it is, if it had crashed back to the stand and damaged things there that would be a setback. If it made it all the way that would be as much progress as you could get. Failing before MECO was less progress than I expected but still progress.
