Stupidity: After a brawl with gunshots exploded in the cafe, and having just seen Jane pull from the backseat a huge gun, Elena is shocked that the bad guy is shooting at the car and even asks "OMG, is he shooting at us?" How does a line like that make any sense, already late in a chase with weapons involved from the beginning? (00:20:45 - 00:22:40)
Stupidity: The bad guy who spies on Bosley is visible from the very beginning of the scene, when Elena is not even inside the cafe yet. The cafe does not have many customers and the bad guy is using a loud vintage typewriter with a big mirror mounted on top (!). The Angels are portrayed as being super smart and their setup is so careful, but somehow they managed to miss something amazingly obvious. Conversely, nobody would have ever paid attention to a laptop or any silent, modern-age device perhaps with a camera or something similar, so the bad guy chose the most blatantly conspicuous accoutrement for his spying job. Try showing up to a cafe punching the keys of a big clunky typewriter and literally everyone will be looking at you. (00:18:25)
