I've finally seen this movie, and it does feel ... impatient. It does jump along to things too quickly, imo. They do lose opportunities to do character development, and without it, each of the new team members feels flat and uninteresting -- they are just collections of their spoken lines. The potential seems to be there for them, but the film doesn't explore it.
The movie seems not to fit together well to me, but I can't put my finger on the details. Generally, it's the color, the action, the timing, the effects; there's moments, but they don't rise very far. The previews show the scenes better than the movie does, such as the early scene with Wonder Woman spoiling the bomb attack at the bank.
The plot was too simple. If BvS was too complicated, and the editing dropped too much of it for most audiences to follow, this one was too simple. There could have been dramatic build-up, but instead, it's boom! and the big bad is all over the screen. There's too much action in it, and not enough storytelling. I don't get the storytelling such as it is, either; as was mentioned up-thread, this was their one and only chance to put the team together, and it was not very interesting. A few minutes' worth of previews told it better, again.
To me, not being a comics expert, the real draw of any movie is the story and character development. No movie without it can succeed, and no movie with it can fail. Good stories let me overlook terrible vfx and camera shooting. Bad storytelling can't be saved by anything else. One story I've looked for all these movies to tell is why is Superman such a good person? The first movie touched in it here and there, but it could have been the centerpiece of the plot. They've had three movies to explain that to me, and I still don't see a compelling reason for it.
I'm sure they'll make more movies just out of momentum, but I'm afraid they're going to go like the Batman movies back in the '90's did.
