Suicide Squad is a comic book movie, it should have issues.
Here's a few to show that the movie did at least follow the comic.
As you can see by the cover, though the Squad members are not on it, they have at least been named, and this release timed to take advantage of the movie.
Plus you get to see the second version of the Doom Patrol working with a doomed Squad, and Speedy and Vixen in action together for the first time (this is cooler more for CW's Arrow fans than for DC movie buffs, but still...).
Kicked In The Teeth
....but Harley was still haunted by the spectre of the Joker in these stories from Suicide Squad #1 to #7 from the 21st Century. This series very much highlighted the illegal side of what the Squad was doing, moreso than before, and the slant of having the series tied a little stronger to Batman's foes (the movie even replaced King Shark with Killer Croc; Killer Croc being a Batman foe who started in the 1980s, and helped to make Jason Todd into Robin).
A little more history of the Suicide Squad with Rick, the Enchantress, Deadshot and Captain Boomerang is here, Amanda Waller and the Incubus is here, El Diablo gets the focus at this spot, Outsider (and brief Suicide Squad comic guest star) Katana is here....and Harley Quinn and Killer Croc will likely get tons of coverage coming up!
Maybe, at some point, people who are at their ends or considered useless by society, finding a little redemption by doing one last brave act as well.
So, while you may be able to say Suicide Squad isn't your cup of tea...
....you really can't say it didn't follow the comic books.
