I just expected more after everyone was saying, "Nooo, it's not a remake. It's something completely new. You will be totally surprised." And now seeing this it's basically the same story just the other way around. Instead of Tarzan ending up in civilisation, he's coming out of it and going back to the jungle. Jane is of course the damsel in distress again. They just put an Oscar winner in it and polished it off with some nice CGI to make it look pretty.
I think that's just the takeaway from the first trailer. Yates has said that Jane is not a helpless damsel, that she's as strong a character as he is. They could have added a few more scenes to illustrate that, though, I agree.
