I wonder if M. Night Shyamalan cast Hayley Mills in Trap because it is about a parent being trapped at a concert. Josh Hartnett’s Cooper/The Butcher isn’t just stuck at that Lady Raven show. He’s held captive by memories of an abusive mother and maintaining a double life as doting dad and demented serial killer. Ms. Mills pulled double duty in Disney’s The Parent Trap some 60 plus years ago. It is nice to see her in a high profile project as an FBI profiler. Doesn’t it, however, seem like the type of weird Shyamalan touch to put her in the picture simply due to the title connection?

M. Night’s Disney breakout The Sixth Sense and follow-ups Unbreakable and Signs still stand as career highlights. You do know that his unnatural dialogue will be a constant and that’s even if those aforementioned strongest efforts. It’s present in Trap, but the wooden acting that often accompanies his thrillers is thankfully missing.

Hartnett, in his first leading role in a while, treats his teenage daughter Riley (Ariel Donoghue) to floor seats for pop sensation Lady Raven. She’s played by the writer/director’s own offspring Saleka. While enduring such a performance might be a chore for any middle-aged dad, he’s got bigger problems. As a kindly and quick to spew exposition T-shirt merchant (Jonathan Langdon) informs Cooper, the whole afternoon gig is an elaborate sting to nab 12 time murderer The Butcher.

That would, of course, be Cooper and he’s phone monitoring unlucky #13 tied up in a basement somewhere. Now he must pretend to enjoy the entertainment while searching for a way to bypass the heavy security and keep Riley relatively unsuspicious. To be fair, daughters that age probably think their dads are acting strangely without believing they’re homicidal maniacs.

This concept managed to put me in an odd and at times darkly enjoyable position. I found myself rooting for Cooper to solve this complicated puzzle and outwit the FBI being led by the former Mouse House child star. It works on Shyamalan’s terms for about one hour. Then it becomes considerably more convoluted and less engrossing.

The cast is not to blame. It’s amusing to watch Hartnett volley back and forth between personalities and Donoghue convinces in her bracelet donning fangirl love for the headliner. Saleka Shyamlan is fine while onstage though her more meaningful contributions unfortunately come later as the screenplay is unraveling.

I’ll make a concert analogy. The first couple of acts feel like Shyamalan playing his greatest hits dependably while not exactly knocking it out of the park. The encores have the sense of that artist bizarrely playing new tracks from an unreleased album. It’s not what we want and it goes on for longer that it has a right to.
