I had two reoccurring nitpicks with the movie while watching it:
1) At times, it was difficult to to know who the villain was. During some parts of the movie, the villain is arguably Aquaman.
2) I'm not sure if it was intentional, but significant chunks of the movie seemed to heavily borrow from two Marvel movies. (This in itself isn't exactly bad, but it sticks out. I felt that Wonder Woman borrowed a lot of ideas from Captain America; at times -despite being enjoyable movies- it comes across as though DC, as a brand, is a step behind Marvel.)
I enjoyed the film as a Tuesday matinee. Without the WB & DC budget, it would likely be an above average straight-to-SciFi-channel superhero movie. Fun movie, but one time of watching it is likely enough for me. Had it opened at a time when something else I wanted to watch was playing, I likely would have skipped it.
Overall, it's a fun movie.
