This game has both gameplay and style. The high amounts of positive reviews prove, definitively, that it has both gameplay and style.

What you have done is cherry picking, a logical fallacy.

Now, if you don't like the style or the kind of first person shooter game this is, well... Those are subjective matters. But you're not talking in subjective terms; you're saying there is no, or a lack of, gameplay. And that is simply put objectively wrong.
