He's not a great filmmaker (though Hercules is honestly surprisingly good-- he's shockingly competent at shooting action), but he's right that Rotten Tomatoes is really, really awful in a variety of ways.

However, in his extended thoughts, he also took some negative tangents about film criticism, tying it together with Rotten Tomatoes somehow if I recall, which... would undermine his point about the value of film criticism and its devaluation through binary aggregation. But then again, he's Brett Ratner, I'm not expecting consistent intellectual thought.
