James Gunn has shown how a movie can be well done if ther is very little interference from studio execs or people who claim that something would be beneficial because its adding a popular character into the mix (cough, Leto as Jokler, cough). This psuedo sequel/reboot/remake hits all of the right marks. Great timing on jokes, amazing effects, enough violence to hit the mark without feeling cartoonish, and GREAT characters.
Idris Elba as a cynical leader, John Cena playing the "patriotic" psychopath, Margo Robbie as Harley Quinn, even hidden gem characters like Polka Dot Man and Ratcatcher all get their spots to shine and have weight to what they are doing.
The story is almost typical "gruff guys become kind hearted giants" story, but this one does it in a much different way. From the bait and switch opening to the bloody ending, its a fast paced ride that doesn't miss a beat, and still has that dark wit from James Gunn.
Definitely recommend checking this one out. I throught the 2016 one was "meh" at best, but this one is a definite "go watch this ASAP".
