Following the 2011 producer controversy over lack of ethnic diversity, subsequent producers committed to including more minority guest characters to represent modern Britain, resulting in incidental diversity in episodes that some viewers criticize as forced and plot-sacrificing, particularly from Seasons 19-24. Specific examples include complaints of wooden acting and convoluted stories attributed to DEI casting priorities.

Themes remain murder-centric with minor progressive touches: a solar park development in 'The Devil's Work' and an eco-village adapting to climate change purchased by a Texan oilman in 'A Climate of Death,' but these elements serve the plot without lectures, identity politics, or critiques of systemic issues. No gender/race-swaps, prominent LGBTQ representation, or creator-stated activist intent. Audience backlash is limited to niche complaints on social media and forums linking perceived quality decline to wokeness, without widespread 'go woke go broke' fallout or dominating reception.
