Watched this with my 8 week old baby, she enjoyed it from what I could tell. It wasn't quite as bad as I'd been led to believe, and to be honest I don't know how I would make a Terminator movie work in this day and age. It's been totally played out and they're just churning the series on the back of nostalgia and fanboyism, so to expect a clear and coherent Terminator movie that doesn't imitate any of the previous ones is a tad unrealistic.
This film messed up the timelines for sure, but do I really care? Nah I don't think so. Terminator 1 and 2 will always be this separate entity in my heart that any sequels can't erase or replace, so if they want to try something new and have some fun with the franchise then what the hell I'll still watch it.
Sarah Connor was too young and hot, lacked that gritty Vietnam-vet look that Linda Hamilton had, but that's a minor niggle. Jai Kourtney was a bit bland, but not this block of wood that some people have made out. Arnie was great, he's still got it
Also really liked the future war scenes and the Skynet complex stuff, very cool to finally see the time machine which had only ever been spoken about in previous films. It was a cool design and met my expectations.
So yeah, I wanted to hate this for raping my childhood memories, but in the end I kinda sorta guiltily enjoyed it for the most part (warts and all).
6/10.
oooh also T2/T1 > T:G > T4 >>>>>>>>>>>>>> T3
Edit: also a word on the visuals - the trailers made it look like a Sci-Fi channel crapathon but the visual effects were mightily impressive for the most part, especially the 1984 Arnie.
