Kevin Hart and a talented young cast serve up a lot of big laughs, inappropriate humor (my favorite kind) and awkward moments in 72 HOURS. Yes it's dumb. Gloriously so and LOL funny unless you are of fragile sensibilities. Then you'll be aghast.

The story is paper thin and predictable, just a flimsy tree to hang some very funny set pieces on, light them on fire and watch 'em go. The cast is up for anything.

Hart (Jumanji, Central Intelligence) is Joe, an advertising exec who's cruised past 40. His last three campaign proposals have been "cringe" to the sensitive snowflakes on the company team. Worried that he's getting out of touch, he decides to attend a bachelor party in Miami for some young dudes that he's never met. In just the first credibility stretch, he's managed to be included in their group text by mistake.

That group is where the film hits its stride, with all four young actors showing the ability to not only hang with Hart, but volley back and forth for serious laughs.

Comedian Marcello Hernandez from SNL delivers as Best Man Nick, determined to have one hell of a weekend in Miami for his bets buddy, Groom to be Mason (Mason Gooding from "Scream"). Their friend Freshman (SNL's Kam Patterson) is dumb as a box of rocks and serves up big laughs with flawless delivery. Freshman may have zero idea what you're talking about 90% of the time, but he's always got something to say. Patterson is a true highlight anytime he's on screen.

Ben Marshall (SNL, Please Don't Destroy: The Treasure of Foggy Mountain) roundS out the bachelor party quartet as Hunter, a heart broken, sensitive guy who's just lost the love of his life.

Watching Hart react to the new generation's attitudes is hilarious, especially when they have "emotional check-ins" before partying and offer up sensitivities that leave Hart's Joe dumbfounded.

When the film focuses on Joe's "old man" vs. the youngsters, it's hilarious, delivering Hart's patented double takes and some great physical comedy.

Anytime the movie tries to show any kind of emotion, like Joe's real motivation for his time with the boys, it grinds to a goofy halt, with the dialogue and interaction stilted and dull.

But when it's going for laughs, the hit ratio is pretty high.

And this is not a comedy for the sensitive. It's a full frontal assault packed with physical comedy, nudity, violence, projectile vomiting, mountains of cocaine and hilariously over the top scenes.

By the time our boys end up stranded in the ocean, using giant whale organs for flotation devices, I was rolling. "Grab a whale dick and swim to the beach!" is a line of dialogue I'm pretty sure I haven't heard before.

Joe rents a Miami mansion for the weekend that happens to belong to a gangster, who just happens to own a yacht....I mean, some of the story connections are painful they are so dumb. BUT when the gangsters are played to the violent hilt by Michael Mando (Scorpion in 'Spider-Man: Brand New Day) and a big star I won't divulge, it makes the groaning story stretch worth the agony.

Teyana Taylor (One Battle After Another) is great but little seen and wasted as Joe's long suffering doctor girlfriend and Zach Cherry (Fallout) drives big laughs as Joe's assistant with a laser focused mind on the female anatomy.

Hart is sure to offend younger viewers (and I cheer it) doing random Tony Montana impressions, binge drinking pepto bismol and vodka and suffering the worst reaction to a jellyfish sting in film history.

There were at least three scenes that take place and then just disappear without any consequence, giving the screenplay a very amateurish, plot hole littered vibe. The tone shifts can make your head spin, popping from violent confrontations to lightweight laughs without any sense of flow. Without this cast, I don't think it would have landed at all.

But thanks to Hart and his quartet of young actors, I found myself laughing constantly at just how far this troupe will go for humor.

72 HOURS hit my funny bone, earning a solid B-.
