Gosh, where to start? MBC sucks for this one. They used Seventeen's rookie status to bully them for entertainment. Some of the challenges were really degrading, and the whole thing with them taking away their food, because they didn't earn it through suffering (or whatever their standards were), was hard to watch. Most of their interactions with the staff were kind of awkward.
Seventeen, though, rose up to the challenge. They did better than anyone on that production team thought, and really stayed together as a strong team. They even handled their mistreatment with a grace that I don't posess. This show would never happen today with Seventeen being so successful. Carats would have a fit.
I'd only rewatch this to see baby Seventeen have fun together, trying to ignore all the BS they put them through.

End of rant.
