I'd agree with you, except Eccleston and Tennant were when the show actually started pushing for something more grown-up. Now everything’s a bit off, with the money men breathing down creative's neck. This isn’t a new problem; Smith, late Capaldi and Whittaker were all aimed at "families." It felt like a watered-down, PG version of Tennant.
Production-wise, it’s still a mess. They couldn’t get Ncuti to commit to a full season because he's busy posing for fragrence ads and Doctor Who doesn’t pay enough.
