If Treasure Hunters looks familiar, it may be because it’s a combination of The Amazing Race, The Da Vinci Code, and National Treasure. The two-hour season premiere of Treasure Hunters will air Sunday on NBC at 8 PM and so far, the buzz is that it will be an entertaining ride among the otherwise blah summer offerings. No telling yet if host Laird Macintosh (no, I’m not making that up) will be as credible a reality host as, say, our beloved Phil Keoghan from Race, but it’s worth a look. Scenic locations, the hunt for clues, physical challenges and abundant product placements all sound promising.
