Matt Forbes’s review published on Letterboxd:
Very conflicted on this one! There are some very charming moments and I do have to admire it for its ambition. The performances were generally pretty great too, especially Roman Griffin Davis, who absolutely killed it. But as a comedy it was kind of mild - there's some laugh-out-loud moments for sure but most of the gags usually only elicited a chuckle from me at best. I also thought there were times where the movie couldn't decide whether or not it wanted to go full-out absurdist, because there were moments of that kind of humour, but these were so few and far between that they were a little jarring. On top of all that, the drama elements felt by-the-numbers at times, and there was only so much dramatic weight the movie could have while also trying to be so consistently goofy (though there was a gut-punching 'serious' scene that was done particularly well).
So basically you could watch a comedy-drama that only really works to a certain extent in both the comedy and drama departments, or you could watch John Mulaney and the Sack Lunch Bunch on Netflix.
