Turn on the closed captioning...once you do, you will be hooked.I'm so lazy now, the CC is on all the time.
As for the movie, it was OK.The special effects and stunts are worth seeing.The different kinds of terminator machines are interesting.The end is confusing;I assume the terminator/human regrows its heart?
As for the whole methos of terminator, if the machines rise up, humans are basically boned...it's as simple as expodential math.Once the machines are making machines, it's over.
