I passed on T4 and T5, i'll probably watch T6 based on this news.
The original Terminator remains my favourite for all number of reasons,
one of them being, the relentless nature of the un_stoppable Terminator
T2 was good, bar two issues:
1. The liquid concept for a Terminator, i didn't buy the idea, no matter how impressive the CGI was for the time.
2. The kid. We went from souless killing machine in T1 to a Terminator that would act stupid on the command of a kid.
T3 was just plain awful. Arnold isn't the best actor in the world, which is why his style worked so well during T1. During T3 Arnold appeared to have got too big for his boots, and instead of acting like a Terminator, acted like a parody of a Termintor, speaking his one liners like a comedian. Kristanna Loken as T-X worked well enough.
