Movie reviewOf the many lessons to be learned from David Robert Mitchell’s new genre-flexible film “The End of Oak Street,” two of the most important are as follows: Do not wear headphones during a crisis, and always listen to mom. In essence, “The End of Oak Street” is a survival thriller dropped, like a boilermaker, into a family-friendly ’80s adventure film, for a resulting concoction that’s perpetually goofy, genuinely scary and somewhat ironically heartwarming. They’re stuck with tamer reference points like “The Flintstones” and “Land of the Lost,” where dinos and humans can coexist. Not so much here on Oak Street, where most of the Platts’ neighbors have fallen to this dino massacre. No matter the censor standards of the day, “Oak Street” is fundamentally a story about a family’s devotion to one another, which would be eye-roll-worthy if it didn’t also feel fundamentally sincere.
