This is definitely enough to get you hopeful McG's film won't be a wash-out, and the way the iconic Terminator theme booms out to the words "THE END BEGINS" punched my geek-button. At the moment my faith in Salvation is the product of Bale's presence. He probably shouldn't be playing another big pop-culture hero after Batman, but I just can't believe he'd choose to be in this if the script wasn't good. He doesn't strike me as a take-the-money-and-run kind of actor.
However, I'm still very nervous because the film's climax (leaked onto the internet by a script spy a few months ago) sounded utterly ridiculous. If true, it's the kind of ending that would spoil an otherwise good film. I really hope it's not true, or they've taken note of the criticism and rewritten it. The producers quickly denied that's the ending they're using -- but that's to be expected. I just hope it's true. Oh, and as much as I've enjoyed The Sarah Connor Chronicles on TV, I still think the loss of Arnold Schwarzenegger is a shame. I hope he gets a fun cameo, or CGI has reached the stage where a digital Arnie (circa '84) can be seamlessly integrated into some scenes.
Anyway, check out the teaser. It's better than you were probably expecting.
