Yes, fat is 'good for you'. Without consuming it, you die.
But I would say that in general, 'x is good/bad for you' is a harmful oversimplification. Sugar is also not 'bad for you'. It's not that simple. Glucose is important and sometimes extremely beneficial to consume (in any form).
As for saturated fat: it's complicated. Correlation != causation. For transfats we have a pretty good idea via which causal mechanism problems arise. For saturated fat we only have correlations. Given how hard nutritional research is and especially how hard it is to draw conclusions from it, I would say it's better to refrain from feigning confidence on substances where the jury really is still out.
