I'm assuming most people are teens here since no one will criticize this movie at all..
Anything with spoiler is a spoiler(FYI)
Negatives:
-Jared Leto's performance: The look could take some getting used to but Leto was just annoying. His mannerisms, to his mix of Heath of Mark's voices were painful to hear. And that damn laugh...he sounds the Count from Sesame Street wtf man. If he wanted to pull off a more "gangster" Joker. He needed to have the intensity of Mark and the subtlety of Heath. I mostly blame writing though.
-The jokes: "oh..you smell like death"
*Crickets* seriously only about 4 of the jokes were funny. Some were painfully delivered at that.
Plot: Very simple and full of glaring holes that didn't even warrant the need of the Suicide Squad.
[spoiler]The main conflict ends with 4 sticks of C4 and a big explosion..again. You could've had a jet fly in and do all that shit in 30 minutes and ended the whole catastrophe[/spoiler]
Characters: Deadshot, Harley, and El Diablo were really the only characters that developed at all. The rest were just there. Also "Deadshot, most wanted assassin in the world." They initially had Deathstroke in this film..did they forget about his profession?
Acting: This will be my last one but it's not a huge one either. Every now and then some lines or moments felt so phoned in and not really cared for.
[spoiler]Will Smith during some flashbacks yelling "No!" was so calmly delivered and had about as much emotion as that damn donkey from Winnie the Pooh. Margot Robbie also had an emotional moment that was just totally botched due to her tone. Leto...ehh ehh ehh ehh ehhhhhhhhhhhh. You spent two weeks and came up with that shite????[/spoiler]
