Well, i highly doubt its the challenges. Watching peple eat and gag isn't what TAR is about O_o. i mean from what I 've seen in TAR3 and TAR4, not one roadblock was eating at least i don't think. Only 1 detour and 1 FF from these two were eating. Their roadblocks were much more exciting such as swimming with dolphins, bungee jumping, selling bowls of escargot, blocking a soccer goal from young professional soccer players, and changing tires of race cars and actually doing a lap with a professional. Also, as many people mention, they were also driving which created so much drama and excitiment, that led teams to be eliminated who were ahead and sometimes even walking to the pitstop led to many teams downfall. This time, it is too straight foward.
