You've nailed the point: you're an HDR addict. But, while it works for some shots, what I like to see is a 'good picture' rather than a 'good technique'. If it's not immediately obvious whether a pic is manipulated... then that's the kind of pic that will appeal to me.
I used HDR yesterday, when shooting the interior of a dark 17th century hall, full of wood pannelling. I wanted to get some detail into the shadows, and the light coming through the windows. The pix don't scream 'HDR'... the technique just made it possible to get the pix I wanted.
I've used HDR on landscapes... with mixed results. Sometimes it seems to work... sometimes it doesn't (and I'm still learning how to tell the difference). Deep blue skies don't seem to work (for me, anyway...): it seems to go lighter and darker around anything, like trees or buildings, that appear against the sky. And strange things happen around telephone wires (as in your pic of the railway bridge).
Extreme conditions - stormy skies, sunsets - seem to take well to HDR. Like chilli powder in cooking... it's best used with discretion... 🙂
