He's still very vague, isn't he?
No. He's being as diplomatic as he can about saying he hated the show.
This is very important to note, and I want to reinforce Bones' point. Diplomacy is needed when you're fairly popular and you've got as many contacts accordingly. As much as we all like to think of film and TV as leisure projects (especially in the sci-fi/fantasy realm), we have to remember that for people like Eccleston, Tennant, Smith, RTD, Moffat, etc that it's still an industry, and every industry needs a degree of professionalism and business atmosphere.
