Just to add my own diatribe to this discussion. Also, apologies to those that havent seen it for the few details this post contains, skip on by if you want to know nothing about this film at all
This film did not work. It was never going to work, it should never have been made.
As a devout fan of the first two films, of course I went to go and see it, I was willing it to be good, it wasn't
I could moan forever about the bad job that McG did, he clearly pandered what should be a very adult themed franchise so that it would get a 12A rating, I dont mean swearing and violence, I mean the general feeling of the film, sure the first two films were gory etc., but there was something missing from everyone, that feeling of menace rather than just "kick ass gung-ho". Things all felt very mad max and thats just not what we saw in camerons vision, we saw the sky blackened, piles of skulls (not just one token skull), droves and droves of terminators, not just one or two clunky ones. Also... why were everyones teeth so damned white?? I hate the hollywood smile, but I know they all have it, however, why would literally every single person in a post apocalyptic future have perfectly white gnashers???
I know this film was set before the flashbacks from T2 and so the terminators etc. were less advanced, and I do appreciate the effort put into trying to make the storyline work with the originals, but thats as far as my appreciation goes.
Putting the terminator amongst us in our time in T1 and T2 was a stroke of genius (we wont mention T3). A single machine whos sole purpose is to kill one person makes them like a murderer, only a murderer that is nigh on impossible to stop, cant be reasoned with and simply will not listen.
Similarly the same ethos applied to a hero makes them a fantastic hero. We needed the vision of the future to explain where the robots came from, we needed judgement day to give the whole thing a feeling of impending doom, but ultimately what we have is a brilliant traditional psycho-esque concept.
However, when there are lots of terminators, judgement day has happened and everyone you see is kick ass and expecting to die, what you have is a sci-fi war, and we have seen many many sci-fi war movies before.
Imagine T1-T3 had never happened, you have never heard of the terminator, you dont have any good childhood memories of arnie etc, then imagine T4, it simply does not stand up on its own, from the terrible CGI helicopters (pet hate) through to the problems with continuity and the weak storyline.
Sure its got some good effects, but nothing new and arguably some worse than things that have come before it, christian bale plays john conner as batman for some reason i can't fathom, even the guy who plays reese is unconvincing and he currently has a brilliant role out in Star Trek, so the guy can act when given the right direction and script...
I'll leave this rant with one final thought, in T2 we saw Arnie melted in standard liquid metal. In T4 we see a skeleton covered in (I assume) liquid metal of the kind they make their own skeletons from, so we must assume its tougher than say mild steel, yet all that happens is it cools as a shroud (clearly going for the grim reaper look) and it breaks free. 10 minutes thought and respect for the original would have shown that bit of script writing to be simply wrong in the context of the originals, yet McG went with it anyway. No doubt because he couldnt be bothered working out something more cerebral and because he thought it would "look cool" to see it clawing at bales face.
Apologies for the long post, I was gnna stick it on IMDB but then I thought I would probably get more discussion here than there so wrote it up here instead!
