The last time someone tried to bring the Terminator franchise back, it didn't go so well. Terminator Salvation was an ugly mess with a glum Christian Bale performance and plot holes big enough to send a Terminator through. That disaster was enough to kill most any fan desire for a sequel - it seemed that the first two Terminator movies would, after that, be permitted to survive fondly in memory, no longer sullied by pathetic attempts to cash in on good will toward it.
Of course, that isn't the case, because Hollywood greed, and this summer will see Terminator Genisys. The only difference between this one and Salvation? At least the trailers for Salvation looked half-decent to begin with.
