there's a lot to say about this show. It was interesting to see 12 year old kids (and older?) doing physical challenges instead of trivia like most other nick shows. The show had a "3 challenges and then agro craig" layout that never got repetitve because the challenges were always random and the agro craig was alsways changing through the series' run. Watching the kids take on this challenges was most of the time, fun to watch. (there were some challenges were all 3 contestants would play at once that weren't so interesting) and could generate big laughs if the kid messed up badly or just has no clue what it is they have to do.
Then there was Global Guts, which was kind of interesting to see international players, but it overstayed its welcome and the series was over after that. (I believe)
