I like this show a lot. The negative reviews must be from people with no sense of adventure. The show is routinely entertaining and suspenseful. The format is typical reality show with repeated scenes before and after commercials, so that's why I say 8, not 9 or 10. Production does need to join 2022, and leave 2007 behind. Having said that, the guys involved in searching for the treasure are fun guys, with real personalities and their methods are unusual enough to provide some edge of your seat moments. Not sure why the negativity from others, but I plan to keep watching.
