I felt there were plenty of candidates to be killed off, so for it to be Poussey (sp?) was bad enough, but for it to be in such an nonsensical matter just made it feel ridiculous and a stupid "gotcha!" type moment. I felt abused by the writing. If she had to go, it would've been far less obnoxious if during the fracas she had fallen and hit her head or something. She just laid there while he barely held her with one hand...and died? Stopped breathing? She didn't even struggle.
It carried no weight with me because there were more than a few other characters that could've been killed that would've had an emotional impact on the arc of the season. Red, Crazy Eyes, Alex, Sophia, Nicky, Healy...the bastard new guard...I felt they all had more going on this season than Poussey. It just felt like a random selection for surprise and nothing more.
