Kick-ass 2 begins with a sequence, attempting to, catch you up on 2010's first film, we find Dave Lizekski (Kickass), Aaron Taylor-Johnson, and Mindy Macready (Hit Girl), Chloe' Grace Moretz attending the same high school and briefly teaming up, which is cut short, leaving the title character fending for himself and in search of a new costumed-partner. Meanwhile, Mindy (Hit Girl) tries to forfeit her alter-ego and adapt to leading a normal life. The recurring villain, Todd Augustus Prew, who now goes by "The Motherfucker," decides to become the first supervillain and attempts to assemble a legion to battle Kick-ass and his newly assembled crew of fellow citizens turned masked crusaders.
The film is also loaded with a lot of humor that appeals to insiders of comics, pop culture and 'coming of age/high school' trials and tribulations.
Eventually (inevitably) things come to a head on both fronts (in real life and on the civilian superhero fronts) with showdowns against the secret identities' nemesis, but then the real action spectacle goes down once the two assembled forces face off; culminating in a epic showdowns involving explosions, physical combat, gunfire, vehicular acrobatics , a lot of moral and life lessons, brutal melee, a lawn mower, and even a mini sharknado!
Be sure to stay after the credits to see what an attempt at supervilliany will get you...
In conclusion, if you were a fan of the first installment, you will not be disappointed by this iteration (But, despite the catch up sequence's attempt at bringing the audience up to speed, seeing the first is almost a prerequisite to enjoying ((not to mention understanding )) the sequel.
