Alternative Character Interpretation: Harley Quinn. Disguises she's helping Joker escape as a temper tantrum or was it only an accident? It gets muddier when Joker prepares to shoot Deadshot in a fit of jealousy, but Harley tries to defuse the situation, if not the bomb, by telling Joker that she was using the Suicide Squad to bust him out of here and Joker is her only man. It doesn't work, but Deadshot seems to appreciate that she tried to save his life. Also helping is Harley refuses to shoot on Deadshot when he and Joker are fighting on a runaway helicopter.
Magnificent Bastard: Floyd Lawton, aka Deadshot, is a highly efficient assassin and master marksman whose primary desire is to be reunited with his daughter. Employed by Amanda Waller as the leader of Task Force X, aka the Suicide Squad, Deadshot organizes an infiltration of Arkham Asylum to acquire stolen information from the Riddler. Throughout the mission, Deadshot displays his cunning and tactical genius as he repeatedly improvises when faced with numerous setbacks by his more reckless and untrustworthy allies, Batman and the Joker, and even fearlessly stares down the latter at gunpoint and bluffs him into wasting his only bullet. Managing to escape via helicopter in the midst of a prison riot while his allies are either killed or detained, Deadshot then single-handedly defeats the Joker in combat, withstanding multiple near-fatal injuries in the process. In the end, Deadshot achieves his goal of reuniting with his daughter, and spends the last few moments of the film scoping Amanda Waller a distance away with a sniper rifle, intent on making her pay for using him.
One-Scene Wonder: The one unnamed special forces operative who fought Batman at the beginning of the movie has gotten some notice and respect from fans for being the one guy in his unit who was able to fight Batman for an extended period of time without easily going down like the rest of his men.
The KGBeast. He dies even before the mission of the Squad starts, only to prove that Waller is the one who holds the power over the Squad.
Black Spider. The guy is a Serial-Killer Killer forced to work with the very people he hates, and something of a Token Good Teammate. He has the least lines of all the main characters, and ends up only serving as a disguise for Batman before he gets killed off.
Too Bleak, Stopped Caring: The developing characters being killed pointlessly midway through the film and the fact that once the Explosive Leash is disarmed everyone completely abandons the plot and runs for the exit can make it difficult to care about what happens in the movie.
The Un-Twist: The scene where Batman swaps costumes with Black Spider is so in-character for the Bat that it would have been a bigger shock if that had actually been Black Spider. Not to mention, as anyone who's played Harley's Revenge knows, if anyone outside of the Bat-Family grabs his belt, they get 50,000 volts.
Many fans found Matthew Grey Gubler to be too low-key and too young-sounding as the normally energetic and older Riddler.
Some people took issue with Neal McDonough as Deadshot, after it turned out that Deadshot's normal voice actor in the games, Chris Cox, was present — itself a part of a huge example of this trope within the greater Arkham series (namely, the series' inability to keep a consistent voice actor for Jim Gordon).
