I personally like the HDR that is not overdone. On the Olympus users forum I visit there seem to be some real masters of this technique and I have seen some and they look stunningly realistic, but in places I have seen some that look so fake and overdone, that to me, they have spoilt what could have been a nice photo.
I have done one (yes, only one) just to try out some free software recommended to me when I was on my photography course. It is a 3 exposure of the Woolworth Building in New York. I hope its not overdone.

This was done using FDRTools software, which seems good for the price
