An action film that bloody well delivers and a Netflix series that updates a Judy Blume classic top our lists of what to watch this week.

“Fight or Flight” >> Director James Madigan’s bone-crunching debut features a full-throttle performance from the underrated Josh Hartnett and irresistibly embraces its B-movieness, encouraging audiences to hoot, holler, groan and laugh. Not once during its 1-hour, 41-minute running time does Madigan let things run on autopilot. It satisfies any action fan’s itch with gory kills, crazy stunts and funny one-liners and facial expressions. Yes, it does travel along on similar plot tracks as, say, “Bullet Train” with Brad Pitt. But where that 2022 confined-space bit of mayhem got snarled up in its own contortions and aesthetics, Brooks McLaren and D.J. Cotrona are content to keep their film planted firmly in a B-movie landscape. There are no high-falutin’ notions about what this movie wants to accomplish, other than giving us a bloody good time … emphasis on the bloody.

Hartnett shows his natural gift for action and comedy as oft-inebriated American agent-in-hiding Lucas Reyes. He receives an offer too good to refuse: A chance to get bounced off the no-fly list, earn back an American passport and receive a one-way ticket from Bangkok to SFO. The demand is that he bring with him an elusive, most-wanted “terrorist” named The Ghost who is on that plane. The person offering the deal is the severe and cold Katherine Brunt (“Battlestar Galactica’s” Katee Sackhoff), a figure from his past. But there’s a big problem with the assignment; the SFO-bound flight is packed with assassins similarly ready to bag “Ghost” for a lucrative payday. It’s a surefire, if not exactly original, setup that doesn’t overstrain your brain cells but affords the room for its actors and a team of stunt performers to brawl, jump, slug, wield chainsaws, and throw deadly darts and cutlery items at each other. And of course someone gets sucked out of said plane. Hartnett deserves a medal for doing some of his acrobatic stunts (your back will ache watching him and stunt performers athletically bouncing about) as do the sound designers who make each smack, punch and crunch sound so real. In addition to the icy presence of Sackhoff to add an edge, Charithra Chandran peps it up as a resourceful flight attendant. She’s a good match to play off Hartnett and is more than game for the fisticuffs and punchlines. But the reason this one flies high — in the nonstop “John Wick” vein — is because of Hartnett. Often sneered at and dismissed early in his career due to his good looks, Hartnett takes over this action flight manual and, well, soars to new heights. Buckle up, kids, you’re in for one a helluva fun flight.

“Forever” >> Here’s a tip for anyone wanting to modernize a lit classic: Consult showrunner Mara Brock Akil. She’s done an incredible job of taking the iconic 1975 Judy Blume classic — an eyebrow-raiser that offended some parents by suggesting that teens have sex — and giving it modern meaning.

Akil’s sexy-smart eight-episode Netflix series turns Blumes’ two lovebirds into Black Los Angeles teens from different backgrounds — the rich Justin Edwards (Michael Cooper Jr.) and the making-ends-meet Keisha Clark (Lovie Simone). They used to be childhood pals but went their separate ways and now attend different high schools. They meet up at a 2017 New Year’s party, and sparks fly.

But both have issues and hurdles to overcome. The people-pleasing Justin is dealing with ADHD and isn’t overly invested in school. He lives in a sprawling home with his overly protective but caring mom (Karen Pittman) and his less rigid restaurateur dad (Wood Harris).

Keisha is a straight-A student, a perfectionist and also the object of social media cruelty. She lives with her overworked mom (Xosha Roquemore) in an affordable upstairs apartment building. Her dad is rarely around since he plays baseball.

The duo fumble about with dating and even resort to blocking each other on social media over miscommunications before they identify as boyfriend and girlfriend.

“Forever” keeps in step with Blume’s style by not seeming like it comes from an adult perspective. That comes through in the conversations (topics include a hit manga series and popular music). The leads also are painfully real with Cooper Jr. inhabiting the uncertain body of a guy who isn’t too confident about who he is both on and off the basketball courts. As Justin gains more confidence, Cooper Jr. reflects that in his more assured stance and walk. He’s an actor to watch. Simone is especially good at showing how defensive and withdrawn some people become when shouldering the burden of a traumatic experience. The first episode is directed by actor Regina King and it’s exceptional. But so are all other episodes in this teen drama that speaks from the heart, the soul and the minds of its teen characters.
