Creationists don't argue things are generically "too complicated", they argue that there are structures in nature that aren't discoverable by progressive mutations. As Dawkins explains in the video, eyes are an extremely commonly cited example. I've never heard anyone argue that cells couldn't evolve photosensitivity, but I have heard plenty of people argue that eyes only work when they're fully functional, which is what Dawkins is explaining as untrue here (as is TFA). I don't find the idea of debating creationism especially likely to be fruitful overall, but answering the question "How does evolution explain the structure of eyes?", e.g., for an adolescent who is grew up in a fundamentalist household, seems entirely reasonable to address.
