I buy smoked mackerel in a vain attempt at being healthy. I do actually really like it, and you don't have to cook it, which is handy.
Kids in general make things fresh and alive and they have this great appreciation for, Holy mackerel, we're making a movie!
There's lots of good fish in the sea. . . maybe. . . but the vast masses seem to be mackerel or herring, and if you're not mackerel or herring yourself, you are likely to find very few good fish in the sea.
