Action sucked. 90% of it is either shooting or poorly shot hand to hand stuff. Best bit was Batman arresting Deadshot in a flashback.
On to the members.
Harley Quinn - Best one. Had some funny quips, well acted and developed.
Deadshot - Surprisingly good in spite of Will Smith. Well developed.
El Diablo - Well developed but doesn't do much until the second half because of this. RIP.
Rick Flag - Kinda developed. Still generic even though he's meant to be important.
Katana - Kinda developed and just there.
Boomerang - Just there to fill quota.
Croc - Just there to fill quota but did have one decent line.
Slipknot - Just there for a minute and gets his head blown off.
Waller and Enchantress were decent I guess.
No opinion on Joker because half his stuff was cut.
5 seconds of Flash. Batman was alright for the one minute and mid-credits scene for Justice League set up (yay /s).
Midway City is where it happens so Hawkman and Hawkgirl could happen down the line.
Also an implication that Harley killed Robin or was at least involved because they had Borderlands intro things and Robin was mentioned on hers for a split second.
Story was generic but some jokes were surprisingly good.
Overall still not enough to give the DCEU a decent film due to pointless characters, **** editting and the final fight being F4 levels of bad in spite of being funny and having three enjoyable characters.
