ok I saw it yesterday and I liked it a lot. It wasn't T2 good (what really is?) but it was the best Terminator movie since T2. Just like jurassic world had a lot of dinosaur violence, this movie had a lot of terminator violence.
It actually went into some time travel scenarios in regards to the terminators going back that fans have been throwing out there for years which was cool.
Some people in the theater made some bad comments about the young Arnold CG but It didn't look CG.... it looked pretty damn real for CG. The trailer gave up way to much of the plot but honestly its a terminator movie the plot isn't that deep. You watch a terminator movie to see killer robots from the future.
Also wait until about 25% of the credits roll by to see a post credit scene
