I thought it was a suspenseless, artificial photocopy of the Doctor Who formula, complete with alternative Rose, Mickey, even an alternative Doctor who "can't die," all under the pretense of "adult," which apparently means random injections of swearing, sex, and spurting blood. For a show that's supposed to be "gritty" and "real," it has an astonishing lack of complexity and refuses to challenge the audience in any meaningful way. The plots (and the music, and...) are tedious and illogical and manufactured to support predictable "emotional moments," and the emotional moments are resolved with flippant ease.
But then I think this about much of the new Doctor Who, also.
