"This isn't a terrible horrible restaurant that nobody should ever go to" seems like 1) it doesn't mean it's actually a good restaurant either 2) the writer might be joking and sarcastic and 3) this will be very rare in actual reviews.
Put another way, certain modifiers contextually go with certain words and sentiments, so why shouldn't state of the art systems lean on that fact, notwithstanding the strict application of grammar?
