I just don't know what to say. Having grown up with the first 2, I'm a big Terminator fan, but having watched 3 & 4, I'm a realistic Terminator fan. I knew going in it was never going to top the first 2, I just didn't want it to be worse than 3 & 4, and it is. It really is. I've seen it twice now and I don't think I can accurately describe how disappointing it is. It runs the gauntlet of prequel, sequel, remake, reboot and parody (of other terminators) never fully deciding on what it is. What we're left with is a convoluted mess that is neither prequel, sequel, remake or reboot, but rather a film that just says "F&%^ all the other ones"
I've heard people say it's similar to the star trek reboot, no its not. Star Trek created a parallel universe in which the adventures of the originals still happened, while their younger selves now travel a new path. In Genysis, the parallel universe only serves to Completely negates everything we've ever seen in a Terminator movie. Which is weird cause they pay homage to the original at first, and then crap all over it.
While the voice over was cheesy, the movie actually starts off strong and shows A LOT of potential, you're thinking "alright, this is interesting." And then, all of the sudden, without any real warning, all that potential is gone and the movie drops off completely. Arnold is nothing more than a caricature of himself, Emilia Clarke (Sarah) is decent enough but the Sarah we know is no more, Jason Clarke (john) is awful and has less charisma than most math teachers, but the worst is Jai Courtney (Reese) whose wooden performance is made all the worse by his odd horse face. And now for the action, eh. What's the 1 thing a Terminator movie has to have in it (besides a cyborg and a Connor)? An edge of your seat, over the top car chase scene right? Yeah, this bus chase does not, IN ANY WAY, cut it. Yes, a worse chase seen than Salvation.
Why didn't they just make a movie set in the future that tells the story of Kyle going back? And now plans for a trilogy, this being part one. Really? Why? (Writing this the day it came out), this movie is probably going to come in 4th on opening weekend, behind a stripper movie, a kiddie movie that has been out for 2 weeks, and another sequel that has been out for 3 weeks. Do you really need to waste more money with this cast and storyline? Mad Max, which was never ever near as popular, both financially and critically, did way better than you and without their ageing star who would've made the movie worse.
