Aside from bad acting, a stupid plot, bad dialogue, and bad pacing, the movie went on 40min longer than it should have. It ended. And then it kept going. For 40 more minutes!
It didn’t help that the best part of the movie was Wonder Woman, who isn’t featured in the title and only really appears in the 40 minutes that shouldn’t even have been in the film.
Sure, there were a couple good action scenes, but two action scenes don’t even make a good Action Movie — and it doesn’t make much sense to pad each of the good scenes with an hour of shit on each side. And they were certainly offset by the shitty stupid action scenes that had no point and went to long. The climax of the movie was obviously a disappointment, despite Wonder Woman’s presence. But one can imagine that Wonder Woman is probably used to disappointing climaxes by now…
