Well, I went to see it. I hated T3 and really, really, really wanted to like this one. During the first twenty minutes of non-stop action and extremely annoying shakey cam BS, I was pretty sure I'd be making a post talking about how disappointing it was. But actually, I really liked it. It had its flaws. The camera movements really made it hard to enjoy. Sure, they want you to be disoriented and to feel like you are part of the action. But I don't want to be part of the action, I want to sit down and enjoy the story. This film was obsessed with P.O.V. shots, all of which had to bob about wildly. That was really annoying. Usually while watching films on my small TV, I think how awesome it would be to be watching it on a big cinema screen, but while watching this thing on the big screen, I kept wishing I was watching it on my tiny TV. The "documentary" style camera movement really hurt this film to a far greater degree than it should have. Crazy to go through all the work to make a film like this, then to try your damnedest to ruin it with creative decisions like this.
The story worked well enough for me. I keep hearing critics talk about the story not making sense, I wish they would be more specific, because I felt it was pretty strait forward. SPOILER ALERT: I assume they are talking about the leaders of the resistence being so determined to destroy the machine factory, even though they know there are hoards of human prisoners being held there. I thought that was kind of weak, especially considering the fact that the human race is suppose to be heading towards extinction. You'd want to save as many as possible, not simply blow them all up as unavoidable casualties of war. Beyond this dumb bit of the story, it all made perfect sense to me. And unlike Star Trek's plot, this one, linear as it was, at least had decent motivation behind it (again, except for the leaders determination to blow the factory to hell without even giving a second thought to saving the prisoners).
I really liked the character of Marcus, and his plot twist was really cool. But unfortunately they felt the need to spoil the plot twist in the trailer, so it wont be a surprise to anyone.
I liked the kid who played Kyle. Perfect casting IMHO. I thought Bale did a great job as Connor. Bryce Howard, an actress I usually really don't care much for, also felt perfectly cast as Kate Brewster.
The vast amount of fan service in this film got old fast. I smiled when young Kyle delivered the famous "come with me if you want to live" line to Marcus. It worked for me, after all, it is the same character. But then the references just kept coming. I felt like groaning when John said, "I'll be back!". I was half expecting him to say, "You're Terminated, Fucker!" during his fight with the T-800 at the end, and was relieved when he didn't. Also glad the line "Hasta la vista, baby!" didn't make its way into the film, but just about every other famous Terminator line seemed to.
Beside the annoying camera movements, the biggest complaint about the film I had was its severe lack of dialogue. A little bit more character development could have been used and would have improved the film immensly. I am hoping there was a lot of this sort of thing filmed that ended up on the cutting room floor that is just sitting around waiting to be included on the DVD. I also have high hopes that we might get an "unrated" special edition DVD, or something along those lines. I can't help but feel some things were cut down to get a PG-13 rating.
Also the ending felt like a "Dark Knight" sort of ending. Very unsatifying. I was fine with the idea of Marcus sacrificing himself to save John, but doing this by having him offer his heart to John was a bit weak. Think it would have worked better if he had died saving John or Kyle in the heat of battle.
A final thing I'd like to mention is Arnold's "cameo". I have to say, it was pretty cool to see him in the film looking pretty much exactly like he did in the first film. But as good as it looked, it looked obviously CG. It looked bad enough now, I'd hate to see how awful it will look five years from now. Ultimately, this little surprise was just another piece of fan service that really wasn't needed. The scene could have worked just as well had a non-skinned T-800 stepped out of that chamber. Nothing wrong with it being Arnold, if fact, it was a cool concept. I just don't think the CG worked that well.
I am sorry to see critics ragging on this film so harshly, especially when they give such high praise to films like "Transformers" and "Star Trek". I think the existence of the Sarah Connor Chronicles may have a lot to do with this film being received so poorly. A new sequel is one thing, but a new sequel and a mediocre television series all in the same year is something else entirely. Too much of something good is never a good thing; too much of something that is just okay is even worse.
Final verdict, I liked it infinitely more than T3. I really hope this is the last film. I don't want to see any sequels. It could have been better, but I still liked it. Certainly not on par with T1 or T2, but it is a nice little spin-off for guys like me who just can't get enough Terminator (except when it is T3, even one second of that film is too long for me). I enjoy this the same way I used to enjoy SW novels. Can't consider it truly part of the overall story, but it is a nice little expansion on the story.
