It's a crass action film that borrows heavily from everything you've ever watched, read, heard and loved. Music, background score, camera angles, action sequences, costumes, special effects, props, dialogues, ideas,... it's a myriad of inspirations. But they aren't executed well enough to pay tributes to the originals.
It may appeal to an audience who haven't read Diamond Comics or watched Hollywood hits. Or the ones who have poor imagination and can't connect the dots.
