These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
They Wasted a Perfectly Good Character: The villains in the first episode, most notably BRIAN BLESSED as Frank Kemble, a self-made London gangster, and his henchmen, as well as Alex Prosser, a struck-off QC who acts as a representative for bigger crooks. The episode spends some considerable time building up relationships between Kemble and his henchmen and Prosser, as well as showing their ruthlessness by having one of Kemble's henchmen hold a hot iron to Regan's girl's face to get her to talk... only to have the Sweeney apprehend the lot of them and Kemble's sidekick shoot him by mistake.
