WW has an iconic figure larger than any character in SS (besides Batman and Joker, but each are barely in the movie, and Batman wasn't in the marketing at all), and being the first solo female superhero film of the modern era, coming off a movie where she was well-received and garnered interest. The marketing may not be 'brilliant,' but nothing about it has been ill-received outside people super pessimistic about the DCEU in general thinking it will suck. The trailers have all mostly been well-received from what I can tell, and that movie is a direct lead-in for Justice League.
So, yeah, WW has enough. It'll do fine.
