i enjoyed T4 much more than the abomination of a Terminator sequel that T3 was (spoiler alert.... a virus....). I occasionally watch it in the style of mystery science theater by picking out all the blatantly obvious or inconceivable physics the filmakers used to move the plot line.... "a crane that can operate everything mechanically from the driver's cabin = wrong"...
I liked this movie also. Previously saw it at a Muvico theater in Rosemont, IL. The sound was off the chart then and I look forward to checking it out on BD (when I get the chance).
I've been to the Rosemont Muvico as well, but I have a feeling that if you have a great setup at home the BD will eclipse the theater experience! My house was really shaking...had to turn down the volume lots of times for fear of physical damage to my living room.
The gas station attack and opening battle are amazing!
