All in all an entertaining episode.
We get to see Watson deal with her relationship with her father, a frustrated Sherlock struggle with his affliction, and get treated to a couple of plot twists. What really made an impression is the searing rage Captain Gregson seems hardly able to contain while making an arrest, displaying the most emotion he ever did throughout the series.
However, as a Dutch science teacher, there were 2 things that annoyed me while watching the episode.
1. While Plutonium-238 does emit Alpha particles on decay, Alpha particles are really hard to detect. Because they are so big compared to Beta particles, they are unable to travel more that a couple of centimeters through air. Seriously, 4 or 5 centimeters of air is enough to stop all Alpha particles. A piece of tape on the camera of your phone stops all the Alpha particles dead in their tracks. Even the outer layer of skin stops most Alpha particles, making Alpha radiation the least dangerous type of radiation. 2 minutes of internet research shows that the app Watson uses actually DOES exist, but only registers Beta radiation.
2. The 'Euros' depicted in this episode do not speak Dutch. Not even close. They say something that vaguely sounds like German, but is actually not. I know, it's really, really hard to hear us 'Euros' from across the Ocean, but for God's sake, hire someone who actually speaks the language before passing some unintelligible mix of Germanic and Slavic languages off as Dutch.
