I'd say the best thing about T2 is the music - that gets me on the edge of my seat more than the visuals. Although that's looking at it from a 2008 point of view rather than early 90's.

I just don't know what to make of T4, from what's bee released. I want to try and just wait and see but it seems like a pretty different flavour to what we've seen. But then I guess the context is that they are preparing for a future [in the earlier films.] that they are actively trying to prevent / alter...So things CAN now be quite different.

Are they still planning on doing Terminator: Salvation as the 1st of a new trilogy?

Re: The TV show, It did start out kind of crap, But it has gradually gotten better throughout the short first season, I guess I'll keep watching and see where things go this coming season...
