Why can't DC make decent movies

Rating: 3/10 (29 November 2017)

First of all a disclaimer, I only sat in for the first hour of the movie. After that I simply couldn't be bothered to watch any more. My rating is based on the first part - it might have picked up tremendously during the second part, but I don't imagine what could have happened during that part to justify a 7.3 on IMDb.
On a side note, I have watched a ton of JL the animated shows, so I feel I know the characters pretty well.
I felt that everything was centered around special effects. The story, I felt, had no real cohesion and it seemed to jump around all over the place. They try to put in a bit of backstory for some of the characters but it's so shallow it doesn't matter.
Affleck does a good job as Batman, as does Gadot for WW. However there is absolutely zero chemistry between Wayne/Batman and Alfred. The flash is too much of a comic relief. As he himself says he has no combat training or anything, and is afraid of everything basically. Where in the world did he get that suit from?? Cyborg is by far the worst character, Momoa as Aquaman is not a whole lot better.
