A Vietnam-era PTSD victim drifts into a small town, the cops pull a “vet lives matter” on him and all hell breaks loose. Voila! Sylvester Stallone has a second franchise. “First Blood” (1982) is a landmark in macho film history, opening a door that guys like Chuck Norris and Steven Seagal walked through (after they closed it back shut so they could kick it down or blow it up). It’s so macho, David Caruso plays a wimpy guy. Hell, it’s so macho, testosterone-spouting Richard Crenna doesn’t need to show up in his Green Beret outfit until we’re 45 minutes in.
