The movie shows that Robert Rodriguez clearly knows who his target audience is. It's a visual feast; the use of CGI here draws inspiration from its spiritual predecessor, "The Adventures of Sharkboy and Lavagirl." It occasionally takes hilarious jabs at contemporary superhero films (Marvel and DC's), is goofy, self-aware, and overall doesn't take itself too seriously. These qualities can be delightful for young audiences, and even for adults like myself.
At its core, "We Can Be Heroes" is a movie that brings to the forefront strong messages about youth empowerment, collaboration, and leadership, which somehow mirrors what many young people are doing today; they take charge in shining a light on pressing issues such as climate change and social inequalities, and making strides to develop sustainable solutions. The message is powerful and delivered crystal clear, which no superhero film has ever done in the past.
