Personally I don't really get worked up over the smaller details. With trailers, they always look iffy on the CGI beforehand, and the CGI work is being done almost up until the release of the movie. So I will just wait and see, and I feel the same about Jurassic World (also having some questionable CGI in the trailers). As for the design of the terminators, I feel like that is nitpicking to the extreme. Sure, the old one looks better, but does it honestly matter that much, a few small details being changed? It still comes down to the quality of the movie. I bet if the ugly looking new terminator was from T2, nobody would bat an eye, because the movie is still a masterpiece. But now that it's from T5, which we have all already decided is gonna be the flop of the summer, then it's easier to bash it.
