Watch the Trailer Here
You can't blame director McG for overloading the Terminator Salvation trailer with all of the film's strongest effects, visuals, and action. He was well aware of the fact that he's no James Cameron, but, rather, the guy who previously directed two Charlie's Angels movies and the gridiron drama We Are Marshall—not exactly great primers for orchestrating T-1000 battles.
For the trailer's purposes, it was either go for broke or keep listening to haters question his involvement with their beloved Terminator franchise, so, understandably, McG and his colleagues strung together a preview that momentarily made everyone forget that Terminator Salvation was directed by a guy who actually calls himself McG on a professional level. All it took to remind everyone of that was the experience of witnessing the film's sheer pointlessness firsthand.
