I know some fans don't have the best view of Daniel because they blame him for every operational decision they haven't liked at the park and sometimes he's overpromised and underdelivered (Mark Twain, Disney Village...) however from what I can see he's been a great driver for focusing on improving the show and guest experience in the park. I often saw him in the parks and I think he attended nearly every attraction reopening following an extended refurbishment, season launch and always acted as the "MC" for the cast member after hours events.
Hopefully his successor will be even better but I think Daniel has done a good job in his COO role.
