There are always going to be new things happening in photography that people are going to like, and dislike.
There has been a heavy increase in over saturated and slightly over exposed images, many people like them and it appeals to them, while there are also a lot of people who like images that are extra dark, heavy shadows, etc...
There are people who photoshop and post process the hell out of their photos and get both positive and negative reviews.
There are people (even like myself) who shoot things out of focus with intention to form interesting compositions. I have met people who like the shots, and people who think they are crap.
So my question then, is why cant Overdone HDR be a new "style" ?
If that's what they want their images to look like, and it's what they're going for-- what's the harm?
