I think that since Karl passed away Chanel is trying to find its new campaign identity (it's been going downhill for the last 3 to 4 years though so it was even before he died), hence the lack of consistency.
I see this campaign as a step in the right direction though, we were all over the boring grey backgrounds and boring model expressions. Spring Summer 2020 was the worst chanel campaign in about 10 years (or ever). This brings a little bit of excitement in me, it's fresh, playful, you can actually see the collection and it wants you to discover more. It's got a bit of Dolce and Gabanna campaign feel to it which I think could work for Chanel.
I liked Fall Winter 2019/20, because it went back to the basics of a strong Chanel campaign, how Karl brought back the brand to life in the 80s with Ines de la Fressange on a white background. Perhaps this is the way forward, what made us love Chanel campaigns in the 90s, a strong beautiful model, gorgeous setting, playfulness and a touch of glam!
