Like most Disney movies, "Big Hero 6" will make you cry just as much as it will make you laugh. When the brilliant 14-year-old Hiro loses his older brother in a horrible explosion, he's left angry and desperate to make the people responsible pay for their actions. In the aftermath, he activates one of his brother's inventions, Baymax, a robot designed to care for people. But Hiro sees an opportunity to weaponize Baymax to defeat the people who killed his brother — which is something his brother never would have wanted. As Hiro processes his grief with the help of Baymax, he slowly begins to realise that it's always better to help people than to hurt them.
