“Containment” (**1/2 out of four) was a mildly engrossing thriller set in England about four neighbors in an apartment building who realize they have been quarantined due to a virus that has eradicated civilization. Or so it seems. Vibrantly photographed and well acted but too derivative of both “28 Days Later” and “The Twilight Zone” to really take off. Horror filmmakers should quarantine themselves in containment and start to come up with some new ideas sometime.
