There is no such thing (for me) as a "good" ad.

I want no ads in my life, ever.

When I need to buy something I look for research, reviews, competition, people who actually used the thing for some time and comment on the thing's weaknesses.

I want to control when I start being interested in something, and when I stop also.

When I need to buy something I need knowledge (weaknesses) and control. Advertisements are exactly the opposite of that.

So... no ad can ever be a good ad for me. Period.
