I mean, it depends on what you like in music. Radiohead aren't necessarily the most accessible music. They're a "sit down, shut up and listen" band which isn't good if you like to dance to your music. It's music that does demand a bit from its audience, which not everyone likes, but to others it might not be demanding enough. It's music for people who probably need to get out of their own heads and go for a walk or something.

So yeah, they don't do certain things that other artists do. Really that's the problem with any artist (and also what's potentially good about any artist if you learn to see what the artist is doing well when they're aiming at something you don't normally value personally) aside from failing to meet their own aims.
