Terminator: Genisys

Changing up reviews. Getting away from star ratings.
Terminator: Genisys Review: The latest film begins in the future previously established in the past Terminator films with John Connor (Jason Clarke) and his friend Kyle Reese (Jai Courtney) defeating Skynet, the A.I. program that ultimately eradicates humanity through nuclear war. Before Skynet is "turned off" it goes through a last ditch effort to save itself by sending a Terminator android into the past to kill Connor's mother, Sarah (Emilia Clarke). John Connor responds by sending his friend Kyle after the Terminator to protect his mother. Kyle is sent back to 1984, the year the first film takes place but he realizes that timeline and events of the first film have drastically changed. Instead of finding a scared waitress with zero combat experience, he finds Sarah already prepared for his arrival and partnered with a Terminator (Arnold Schwartzenegger) that was sent by an unknown party to protect her back in 1973. The three join forces to leap throughout time to once again fight Skynet that keeps correcting its failures as time progresses to the inevitable nuclear destruction known as Judgement Day.
What worked: The expansions of time lines are explained well throughout the film. Arnold is a pleasure to watch as the Terminator a role that was rather joyless to watch in the 3rd installment. Skynet's new plan to succeed is interesting even though it was sadly spoiled in the trailer.
What didn't: Much like Jurassic Park, you can only play "what if" so many times within this franchise. It's on nonstop loop. The Terminator travels back to kill someone to prevent Connor's birth, it fails, Judgement Day happens, Connor defeats Skynet and the Terminator travels back in time. I accept iconic roles are hard to recast but Emilia Clarke didn't sell herself as tough and Jai Courtney is just simply awful. He has the charisma of a toaster.
Final: I recommend seeing it. It's a good movie for nostalgia purposes and watching Arnold back as the T800 is a lot of fun. But after this? No more please unless the next one finally breaks the cycle.
