at what point did you think 'oh crap, its not good'

The opening T2 recap and CG deage Linda/Arnie/death of John was awesome imo so was fully on board for it being the 'real T3' (good to see Eddie get whacked! and its not like we hadn't heard about/seen the death of John before so no big sin really in the mythos)

Then the focus on Grace, Rev, Dani and family... ok the action is pretty hard core so its all good so far..

Sarah turns up and saves them.. awesome..pretty cool..

Then I think after it goes off the boil.. I just do not care about those damn Grace and Dani characters!.. but the Legion twist was pretty interesting

Arnold turns up and he's like a human?! Well it least it puts an interesting spin on it..i guess? but hes the one been sending texts to Sarah all along because he feels guilty? and she been killing Terminators?! WTF?

Then all the plane action with Arnold fighting the T1000 type and its like 'man I seen all this CGI plane action stuff already in FastFurious,Mummy etc and Arnie as a good T800 vs a T1000 type 3 times before already..'

So maybe had the plot gone elsewhere after Sarah turns up.. like instead of the reformed toxic T800/Carl sending texts to Sarah we find that its still out there laying in wait and gets reactivated and Sarah has to deal with a bad Arnold T800 in addition to Rev9.. see where that goes – leading to a far darker path than the usual they take on Skynet and win/save the future ( maybe something where by the time loop being unavoidable so in order for humanity to have a chance they have to change the future back to skynet over Legion wiping out humanity..and a conclusion similar to the previous T3?)
