Good movie but it could've been better

Rating: 7/10 (1 August 2016)

There could be some spoilers, but I will keep them to a minimum.
The movie premiered in my country and I got to see it. I give it a 7/10.
What bothered me: - Not much big villain character development for us to care at all. Couldn't understand who the hell is the enchantress' brother and his connection to her, and they barely appeared in like 1/4 of the movie, didn't care much about them. - Not enough focus on the special abilities of each member of the squad and what makes them special and different from each other. - Not enough Joker presence, but I understand he wasn't supposed to be over-present in the movie.
Joker was great for me and Harley Quinn is the best in the movie. Viola Davis (Waller) and Will Smith delivered outstanding performances.
