Where's the fun and tension in a show where characters always act rationally and with cold and calculated precision? Sounds like a recipe for boredom to me!

No, humans aren't computers. We don't always make the most reasoned of choices even if we like to think we do. Watching the show with a survivalist mindset can surely only lead to futility and frustration in the face of such characters.

That said, I do think the chaos that descended upon the prison in the last episode was a bit much. You'd have thought they'd be a bit more organised by now. I'll admit I got a shock by the conclusion; but I was glad that the writers tried to reinforce the gravity of the overall scenario instead of turning the show into a straight shoot and hack 'em up fest.
