Saw it today. I didn't see as many references to 3 as there were to 1 and 2 (at least directly). It's official, timeline is fubar now. And there will be more if there was any doubt. Besides the ending, you did stay for the mid credits scene, right?
IMO, it does seem like they sacrifice the CGI for the story. When Cameron shot 2, you knew liquid metal wasn't real but it
looked real. By 3 it was more "action" than story. This one was action at a good pace, but a lot of shots you could tell were green screens that could have been cleaned up better to look more real, if not plausible. I know in part it's the way we keep aging actors in the franchise (along with film insurance/budgets/etc) but it just seems to be sacrificing being timeless to remain current.
Overall, great fun flick though.
