I won't lie, the trailer hasn't blown me away. That's not to say there aren't good bits and pieces, and there is still reason to be cautiously optimistic with the cast and Miller. I like the look of the characters so far and will enjoy seeing Sarah again I'm sure. It seems to fall into the usual trap of upping the ante. I could do without this. Give me a dirty, gritty low budget affair. Too much day-time stuff here for my liking too.
This film could still pan out well, but I feel it's struggling with the enormous climb of silencing 3 films worth of squandered potential. Nearly every 'new' idea has been tried and wasted before, whether it's a liquid/skeleton combination (T3), a human/machine hybrid (TS), or an aged Arnie model (TG). There is potential to do much better with these elements this time around, but I can understand the lack of enthusiasm from fans. There's not a lot to latch on to at the moment.
One small but important thing I enjoy is Sarah's commitment to protecting our new protagonist. "I was her". It points to a heart in the center of it all, which has been sorely lacking of late.
