You gotta take everything with a grain of salt until you see it yourself, of course. I'm taking the (so far) overwhelmingly positive response as a sign that the movie at the very least doesn't flat out suck. Which for some people may be a given, but I think that's actually a pretty big thing given that this movie had every potential to be the worst aspects of Snyder unleashed into one hot mess of a movie. It's also encouraging to hear that Affleck, Jesse and Gadot seem to be getting a lot of praise considering they were all heavily criticized bits of casting initially.
I'm in "cautiously optimistic" mode.
