The protocols are the most ignorant move on the whole movie. Firewall 1 2 3 are useless. First, the specimen dies, then they revived it, killed one of them, from there,it should be a lockdown, kill the specimen, saving everyone is not the protocol, saving earth is. Or, dont revive the not responding specimen, you dong what it is capable of.
They couldve written it more differently, i mean, they cant kill it, why kill it again? Waste of time.
