I'm a huge fan of the Terminator movies. Over the past six months my girlfriend and I have watched the all the previous installments, as well as the Sarah Connor Chronicles.
But this piece of the puzzle was probably weakest... or at par with 'Rise of the Machines'. The idea of Marcus is pretty great, but the pay-off somehow wasn't as big as it could've been.
The movie felt more like a Vietnam War movie at times, than a Terminator movie. But then how many new story lines can they possibly invent to tie all these different things together?!
