I honestly don't know. I like everything that I've seen from the Wonder Woman movie so far - from the casting, to the set photos, to the first trailer. But quality of the trailer doesn't always translate into quality film. As always I'm keeping an optimistic outlook prior to seeing the final product.
I will say this though. Warner Bros. is at least trying to fix some of their problems with the DCEU. They realized that they needed a DC equivalent to Marvel Studios' Kevin Feige that knows the comic book world by heart and has the vision to oversee the entire DCEU. So they created a DC Films division
[1] and put Geoff Johns in charge alongside Jon Berg.
The thing about Wonder Woman though is that they're already wrapped filming last May. They'll probably have one standard reshoot down the line but for better or worse, not a whole lot is going to change. Same with BvS and Suicide Squad but that's another topic entirely and I won't bore you with my opinions on it.
