Virtue of the Vicious - S1-E10
Revealing mistake: The first time we see the raid on the senator's room, 2 security guards are shot in the head. The blood spray from the second one emerges a fraction of a second before the gun fires. The second time the raid is played out, everything happens exactly the same way, but this time the spray matches the gunshot. (00:11:10)
Revealing mistake: Mason brings his unnamed son to the lake and acts like he is going to drown him. The baby is noticeably a doll in all but the scene where he kisses it. It is obvious from the way he is carrying it as well as the lack of movement.
Revealing mistake: Towards the end, when Luca and Deacon are bringing the criminal they caught to one of the cars, he has his hands tied up over the hands themselves and not at the wrists, making that kind of restraint completely ineffective. (00:38:30)
Lead Horse Back to Stable - S1-E11
Revealing mistake: When Danny and Colleen are fighting in the rain at the end of the episode and Danny starts explaining how they should stop fighting, raindrops from the camera can be seen dripping from the top left of the screen.
Revealing mistake: Some of the punches don't land when Linc and C-Note are fighting the bad guys in the garage. This despite the sound indicating they are landing.
Ashes, Ashes - S1-E6
Revealing mistake: It's pretty obvious that Scott Glenn, the actor playing Stick, just has his hand wrapped up to look like it has been cut off. Both his hands are at equal length when his arms are down by his sides.
Revealing mistake: The scene is set in Boston, MA, USA, but at a murder location, a European-style circular power outlet is visible through the glass doors at the bottom of the concrete wall. (00:01:20)
