Agreed, it looks like a painting.
I think it's a good example of overdone HDR... But I think that these types of photos DO have a place. Cartoony looks, to me, are cool even if some don't like them.
I see HDR as a way to take a picture with high contrast and lots of shadows/bright areas, and end up with an image in which you can easily view the shadows/bright areas. That lighthouse photo is an excellent example of it.
