I'm not sure if the 1st/5th Doctor era formula is working for NuWho. Where the Doctor and pals are mostly observers and are never in any real danger. I'm afraid that Series 11 might be remembered down the road the same way Season 19 is - a bland, pushover Doctor, and three-too-many companions who are lacking any personality. Except this time, they're not even killing one off for dramatic effect.
