Wonder Woman! The final 'trinity' movie in DC's universe. I must speak of what first comes to mind - the cinematography. The entire movie looks beautiful, from the orange beaches of Themyscira to the colours of the poison gas, 'Wonder Woman' is designed perfectly.
The movie is flawlessly integrated into history, with real parts of World War One (such as General Ludendorff) playing key roles in the movie. Perhaps what is done well (where its predecessors fell) is the structure and pacing of the movie - each act builds up to the final climactic battle between hero and villain. There is no over-cluttering of characters and plot points, a feat that makes this movie great. Instead, there are very few characters, all developed well with enough dedicated screen-time.
The film's key strength is its era; those engineering the war are very dismissive of Diana due to her being a woman (a historically accurate feat). How so that the movie ends with Diana being mankind's only hope! Please do yourself a favour and see this film. It is the DC Universe's first truly outstanding piece and DC's best movie since 'The Dark Knight'.
