Good show--favorite season since Season 1--unsatisfying ending though. **SPOILERS AHEAD** Instead of any higher ups being held accountable, the only retribution is found in what happens to a bunch of cancer researchers (as opposed to corporate heads at Silver Sky mine and Tuttle United). But I suppose Season 1 was similar in that those truly responsible and capable of replicating the evil are never held accountable. But in some way it's reminiscent of the real world. Those lower in the chain of command, like at Abu Ghraib, get punished while the truly evil ones get away with heinous crimes. And hey, this way we get further seasons as well--a la, what's the Tuttle Foundation going to get up to next? I think I just need a solid season of the Tuttle foundation getting what's coming to them though.
