Are these people blind?

Rating: 6/10 (24 November 2017)

Let's ignore all the spoilers and make this simple as possible. Movie was...bad? I was more than just disappointed , especially if day before watched Thor:Ragnorok, which wasn't perfect but a little bit better.
Issues: Batman is getting worst, I mean people did not like BvS, I'm one of those who actually did like the movie, but Batman was kinda alright, I even liked his darker tones, but in this sequel (basically it is) he is..confused? It seems like he is confused how to react to people who is now around him.
Team of what? I have read a comics, but even for me it would be more interesting if I would know original story of characters, in this Justice League you get new characters and have no idea who they are, what their motive? Even in comics, those characters have different original stories depending what you read...so you don't connect with them...I did not mind cgi, but story was half-baked and you can blame studio or director swap, but to be fair movie just seemed that will fail from beginning.
So for me question was...how studio? or directors could not see that this would not work? I will probably re-watch movie at home some day, but it wasted potential, especially because there was really nice (simple) jokes, it was fun to watch Flash, Aquaman, Batman (to be fair they could add more those small jokes) but it wasn't enough.
