Really great right up until it's infuriatingly bad (SPOILERS)
I through this on because I enjoyed the Chevy Chase Fletch flick, I like Jon Hamm a lot, I figured this'd be a mild dose of fun at worst.
Well, it was better than that. The one-liners are fantastic and Hamm does a marvellous job with the material. It's not like watching Don Draper in a Laker's hat, he really does great work with the character.
The characters are actually all great. Each one is unique and quirky and fun to see interact with Fletch. Eve, Griz, Monroe, the Countess (Marcia Gay Harden owns it here!) - they're all fantastic.
As for the plot, it was humming along. A really great mystery, interesting list of suspects - the whole thing was really working...
...and then the finale came. Herein lie the SPOILERS.
Fletch corners Angela and Horan on the boat, unspools the mystery, and gets it dead wrong. He's corned by Horan and gets his butt saved by Griz. Munroe and Griz (mostly Griz) put it all together. Oh, I cannot say how wonderful it was having the main character of the film ultimately have no effect at all on the plot or the conclusion thereof. It was great. Such a great choice. Streetwise investigative reporter Fletch just fails his own movie.
Now, I'm okay with bumblef*** main characters who are ineffective. They can be used well. But Fletch isn't one of them. I don't know if the book goes down the same path - I haven't read the books - but at least from the first film, I know Fletch tends to have a little something to do with the solving of the mystery.
Just in case I didn't get the point, the movie makes sure to underline that Fletch had nothing to do with it in a speech with the cops where Griz makes sure to underline that she was the one who really solved everything, not Monroe. And, in case I really didn't get the point, Monroe then throws in a line about how he wouldn't be allowed into the yacht club, but Fletch is (Fletch's "Because you're Jewish," line was at least funny). So, it's pretty unsubtle at that point.
But, don't worry, the movie still thinks the audience is stupid and needs to be lectured, because they make sure Griz lists Fletch's unsavoury qualities and "white privilege" is among them (as though this is a personal failing, like he chose to live in a society with racial prejudice). What really drove me nuts is that the film didn't need this. They had a great, diverse cast, with great roles given to women and people of colour. The movie was just intrinsically being inclusive. Why turn it into a soapbox lecture!?
So, to sum up: a great movie right up until it creates an ending where the lead character has no effect whatsoever and then it starts lecturing us on social politics for the next five minutes.
The denouement is reasonably fun, anyway, with the final fate of the paintings, but that climax is just awful.
