Not only balanced, but constructive and well thought. Saying "this sucks" or "I can't believe anyone invested in this" is useless. The above criticism, while not very constructive, is still grounded in facts (that I can't judge since I don't know the field enough) and goes beyond "this won't work"

Yep exactly, a good mix is "cool but make sure you think also at <constructive critics about what could be dangerous>".
