This show began as a very innovative reality show is a field of television time waste. The initial tasks were intellectually stimulative. The initial teams were engaging. As winning teams won more and more matches, one developed favorite teams and contestants. The show had potential.
But as is the case of many a television success, they milked a good idea to ruin. The show split to British and USA versions. Show hosts changed. The tasks became less compelling and more contrived. The search for scrap became more obviously a search for "Easter Egg" stashed finds. The killing blow was the reliance on established teams.
Without the sparkle of new "Average Joes," the show took on a whole staged atmosphere. Contestants became just bad actors. One found it hard to relate and the "Reality" of the show was lost.
If you can catch an early episode, try it. Do not judge it solely on the later episodes. Junk can be fun.
