Mmmmm, i thought the opposite, he seemed quite serious at times.
Thought it was an excellent episode and am pleased to report that NPH was quite awesome in this - i just remember him been dire in Matrix Resurrections.
Musical number: fabulous! Just like Buffy, Scrubs, Strange New Worlds, Doom Patrol etc and other shows that have done a musical episode - this fitted the moment and fitted the character of the Toy Maker. Although NPH can sing - dunno why they had him miming the fricking Spice Girls!
I thought Ncuti with the fairground hammer was brilliant, very clever, "You get a prize honey" - lol. We give DT the happiness he deserves and yes, it seems it isn't the last we'll see of him - yey!
I did roll my eyes at the wheelchair accessible TARDIS, but then thought, "Why not?" - makes sense in this day and age.
I thought we may have seen DT checking in on Rose Tyler, but that may have been too complicated and a final goodbye to DT, so i can see why that never happened, for now.
I hope Ncuti will be a good Doctor, although i did struggle with his accent a bit on some words. I liked his take on DT's "What?" to "What if?". And, The Master!!!
