Confusing

Rating: 3/10 (6 June 2009)

I for one enjoyed T3 and of course T2 and T1 but i am surprised more people haven't commented on the confusing moments of this film that does not make sense.
1) Who the hell was that kid with Kyle Reese? And why and what was that kid doing there?!?
2) Why was Conners wife/girlfriend pregnant? I don't think that would be something that would happen when the would is ending and you are running for your life.
3) There was no mention of any of the three previous films i.e sending Reese back, sending terminator back to save Connor etc.
4) If Marcus was the one who killed Connor's mum and dad and was there to kill Connor then why did Arnie's character show up and try to kill Connor? these things and many more questions are going through my head as this was one of the most confusing and poorly written films i have seen.
