I have no problem with he new Doctor in terms of his skin colour. I also nostalgically long for the days when The Doctor was asexual, if only because romantic subplots or arcs irritate me - they always start to dominate the show/movie and relegate the other plots and arcs to a background for the love story (the later Tennant/Piper episodes started to go that way). The only problem I have with Ncuti Gatwa is that I still think he's a bit too young. The Doctor should have a certain gravitas which none of the younger actors can quite achieve.
