What his videos are lacking in my opinion is the quality of scenario and planning. They build an expensive set, give away a large prize but the challenges are either too simple or not very creative. Too little challenges, too little competition, too little motivation, too little expressing of personality like mutual help, sacrificing or betrayal, too little unexpected scenario twists. In this aspect they are not as good as TV shows. As an extreme example, take "give away money to random people" series. What fun is in getting money for nothing? And watching that is probably 100x more boring.
