There is a list online with several American shows that inspired British versions, but they are mostly non-scripted shows, such as game shows or reality shows. One notable exception was Law and Order UK. I assume in all of these cases that the cultural differences called for the British version as opposed to simply importing the American version, which is what usually occurs.
I usually prefer the British originals instead of the American remakes, but I also prefer the original shows instead of reboots. The originals just seem to gel better.
I haven’t heard of this Ghost show. I will have to check it out, both versions.
