“Confess, Fletch” is a reboot of the affectionately remembered Chevy Chase films based on the series of books by Gregory MacDonald. The post for the new film, with Jon Hamm as the title character, is charmingly retro, evoking the style and font of the 70s. The film, from writer/director Greg Motolla, is not as effective as updating the character and settings. Motolla, the gifted director of films including “Superbad,” “The Daytrippers,” “Adventureland,” and “Paul,” has an exceptional gift for combining action, comedy, and heart, often episodic with a collection of engaging characters and always with a terrific score. But the character of I.M. Fletcher, smart-mouthed, twice-divorced investigative reporter, is never effectively updated in this intermittently enjoyable film, and the episodic screenplay drags, especially when it assumes the characters are more appealing than they are.

Hamm, who co-produced, is well cast, with great comic timing and all the charm his character needs to get away with behavior which ranges from smart-aleck to obnoxious. There are a couple of tough balancing acts in bringing this movie together, and both work only intermittently.

The first is balancing the expectations of the fans of the original films with the very different environment of the present day. The earlier films are very much of their era and not familiar or translatable to the world of 2022. Fans of the original will want to see their favorite parts on screen. People new to the character will need learn who he is and find him appealing. The poster leans toward the former, with a 70s-retro drawing that looks like a book cover.

And then there is the balance between the comedy, mostly based on Fletch’s smart-aleck quips and romantic escapades, and the mystery, which has to do with some stolen paintings worth many millions of dollars that happen to have been the property of the father of the woman Fletch was seeing and thinking of proposing to.

I’m not sure if it says something about our time or if it just says something about the lack of ideas, but we’ve seen a number of “whoops, my rental is double-booked” storyline in movies lately (see “Alone Together” and “Barbarian” for example). Fletch returns to the US after his time in Italy, planning to work on a book. His beautiful girlfriend has arranged the rental. Small problem: someone else is already there. Big problem: she’s dead. And so in true movie fashion, Fletch has to get out of trouble by solving the mystery himself.

There’s a shaggy dog quality to the storyline, as Fletch drifts from one encounter to another. Some are fun to watch, especially his interactions with a grumpy editor played by Slattery. Some are less fun, like the wonderful Marcia Gay Hard, stuck in an impossible role as the vampish stepmother of Fletch’s girlfriend. Their scenes together are among those with actors who appear to be acting in different movies when it comes to the tone and pacing. And the ending could so easily have been more satisfying instead of ridiculous and borderline nihilistic. As entertaining as it is to see Hamm in the role, the conclusion leaves a sour aftertaste.

Parents should know that this film has some mature material including alcohol and drugs, very strong language, and sexual references and situations.

Family discussion: In what ways is Fletch trustworthy and in what ways is he not? Was what he did at the end fair?
