Some spin-offs can work very well eg NCIS from Jag. But on the strength of this episode I don't think I would ever want to watch Finder.
It was very clumsily done, making the Jeffersonian team look a poor second to the Finder. I found all the three characters irritating especially the girl with the appalling accent - interesting to note that when the series was reworked she was replaced!
I don't count this as an episode of Bones, but did enjoy the opening shot of Booth and Brennan whizzing through the Everglades!
Sorry but it's a big thumbs down from me.
