“The Lockdown” (** out of four) was a relatively routine prison melodrama about a brother and sister (Leo Howard and Caity Lotz) who are stuck in incarceration for a crime they didn’t commit and reconnect with their estranged father (Michael Biehn) who trains them for televised kickboxing fights against other inmates that could potentially result in their freedom. Predictable movie covers a lot of familiar territory from multiple other films but hard-hitting kickboxing fight scenes give this a boost and make it watchable. Biehn is solid as usual as their father and trainer.
