I think the game itself is not exciting and this is the main reason why the show is not attractive and boring. Unlike the "Millionaire" in the ATV before, it involves no questions and answers/challenges and relies only on luck of the participant. SO it should not the totally the responsibility of the MC no matter who it is. Instead, the one who designs the game should be blamed.
Talking about the MC, I guess people like Cheung Kin Ting or Micheal Hui are already the best ones that TVB can hire, as those more attractive persons like Jan or Wong Tsi Wah may not be interested in such programs and the pay they ask for may not be affordable by TVB.
