First off, if you are going to see Wonder Woman, you really should shell out the extra bucks for IMAX 3D. It's worth every penny. There's lots of zinging bullets, arrows, and incredible shows of strength that 3D is meant to carry.
Second, it was hard to pick any one scene that was good, as they were all incredibly high quality. The story by Zach Snyder was tight, and the director, Patty Jenkins, did an amazing job putting the story arc down and giving us a reason for Gal Gadot's superhero to have a bitter taste about mankind.
The story begins on the island of Themyscira, which is showcased beautifully by an island location that looks straight out of a Mediterranean paradise. Hidden from the world by magic, we are introduced slowly to the character of Diana, who (like her Roman namesake) is a goddess in her own right. But we all kind of knew that, because how else could you ever explain Wonder Woman's powers and not make her a goddess? She (rightfully) is as powerful as you'd expect any immortal being to be.
However, the origin story is not without its faults. One of the things that Brad pointed out to me was that (for DC) the Greek mythology and the gods are now canon, the same as the Norse mythology did for Marvel in Thor. This bugs him because it puts that particular religion on a pedestal and makes it more "correct." Begrudgingly, I agree with him. But, if it weren't for the strong mythological background, I'd argue that Wonder Woman wouldn't be nearly as famous as she is. People like it when superheroes have powers that can be "explained" within the framework of human knowledge. They also like it when the costume has meaning, instead of just some red spandex. With Wonder Woman, her braces are an echo of enslavement, her headband is a nod to their greatest warrior, and her belt is a nod to the belt of Hercules.
All of these things have meaning, which just serve to make her more of an icon.
1) I missed seeing Wonder Woman flying around in her invisible jet. I've heard that they are already planning a sequel that will take place as another "period" film (probably this time against nazi's in WWII). Maybe we'll see it then.
2) I loved that they showed Wonder Woman flying. In the comics, she's always flown around (sometimes with great magical golden wings). It's about time that they embraced that dynamic instead of just showing her jumping really far.
3) I like that they established she was a goddess. In the comics, Wonder Woman becomes the new god of war. So this seemed to be a great fit with the written material.
4) I never get tired of the lasso of truth. I love how it glows gold and seems to respond to her thoughts.
5) I was disappointed that the "god slayer" sword was just a sword, albeit a well crafted one capable of sundering pillars. I was kind of hoping for some awesome magical sword that she could cut Superman with in Justice League.
