Good? Yes. $9.50 Good? Probably not.
I was really hyped to see the film myself, being a avid fan of Terminator series. But I must confess, I honestly wasn't too happy with the choice of John Connor in this series, considering how much of a D-Bag I feel Christian Bale to be (I mean, come on.. "Don't trash my scene"? What are you, 9?). However, his acting was fairly good I must admit for this role.
Were I was really nit-picky honestly was the cookie-cutter suspense. Everything had a certain level of predictability about it. We honestly knew the "Twist ending" of the film, which I will not ruin for readers of this review, before it happened. Also, the explosions were unnecessarily loud, and almost ruptured my girlfriend and my own eardrums in the theater. Crank it down to a dull roar please.
Aside all this, the movie was fairly enjoyable. Try to catch the matinee if possible. I think you'll be much more satisfied if you do.
