Expedition impossible was fun. Each season in a different country would have been interesting but without the equalizers it had the same problem as the first amazing race season, 1 team dominating and running out ahead. It became too predictable. Teams of 2 are more relatable as well.
The Alaska experiment / Out of the wild is the survivor alternative to expedition impossible. It was pretty interesting, single team dynamics for a change. Cancelled too of course, it made 3 seasons. Ultimate survival Alaska is still on, 4 teams of 3 competing in a race across Alaska. Didn't grab me, Alaska is overused.
The one great alternative to the Amazing race was The mole. But they fell in the B list celebrity trap to make it more interesting instead of stepping it up like the Amazing race did. Last season they went back to the original format, but only featured 2 countries, then it disappeared.
