Welcome to a trilogy of reviews I call "Revenge of the Reboots".
I imagine that the genesis* of "Terminator Genisys" went something like this: Two screenwriters drove into Hollywood on the same day, each with their own script for a planned reboot of the 1980s James Cameron time travel action franchise, Terminator. One screenwriter had this cooky plan of rehashing the plot of "Terminator 2: Judgement Day" just with Arnold Schwarzenegger raising Sarah Connor. Another screenwriter had a completely different script imagining a reborn Skynet reappearing in 2015 using our iPhones as a new terrifying way to start Judgement Day. Then these two screenwriters, both rushing to make their meeting with the execs, smashed their cars right into each other. Both were tragically killed, most of their scripts were destroyed in the fire. But the execs were able to salvage the situation, they simply took what pages survived of each document and paperclipped them together. Then it was time to make a movie - a disjointed, confusing, riddled with plot holes movie.
Guess what? "Terminator Genysis" is the piece of crap. The Terminator franchise has been long suffering, with "Terminator Gynisis" marking the third attempt in the past twenty years to turn these movies into a bankable annual phenomenon. "Terminator 3: Rise of the Machines" could only regurgitate "Terminator 2" only with less success. And "Terminator Salvation" was the kind of movie so bad that if there was any justice in Hollywood, the word 'Terminator' should have been banned from film titles for a century. Maybe our children's children would be able to undo our mistakes and atone for the sins of that travesty. Yet here we are, just six years later, with yet another attempt. And if the goal was simply to show that it is possible to make a Terminator movie better than "Salvation", they succeeded. If they had any further goals, well... that's a shame.
