I think the corniness begins and ends with him. I also agree with the anti-climax sentiment. They really should've fleshed this idea out more. What executive thought that the criminal underground of Hawaii would be interesting? I'd say pick a more dangerous tropical location like Bogota, but that show would end too quickly. Also, I think if you had several BH "teams" and followed them all around, you might get a show.
Hell, COPS follows an entire precinct for a couple of days edits out the uninteresting police stuff and you still watch drunk and disorderly calls or the scenes where they arrest a woman because there is a warrant out on her for a violation of a restraining order. You know there's a problem with your show when you have to refine it to be more like COPS.
