Warning: spoilers ahead.
That's right. We now live in a society where watching trailers is a dangerous game. The new Terminator: Genysis trailer has been released and not only does it include some serious action, it also reveals a massive plot twist to fans. It seems that this installment of the Terminator franchise will do away with all of its predecessors' plots because John Connor, savior of mankind, is now the bad guy!
Although this might seem like a little factoid that would be saved for the movie, it has been revealed in the trailer along with a whole lot more information regarding the plot. The characters seem to travel back and forth in time (literally or just in flashbacks TBD), but like the first movie, Kyle Reese travels back in time to 1982. This time, however, Sarah Connor is aware of his mission. The next scene shows an '80s Sarah talking to her then-young son only to flash forward again, revealing a grown up John as the new Terminator! Mic drop.
