Here's a lovely, well-turned description. OTTO points at people he dislikes as if they were burglars caught outside his bedroom window. He is a particular flavor of curmudgeon. (Tom Hanks version renamed him Otto "A Man Called Otto" while Ove is the original Swedish character from Fredrik Backman's book and the 2015 film. Either way, same soul underneath.
What gets me about that story is how the grumpiness is never really the point, it's armor. Ove aka Otto isn't bitter because he's cruel, he's bitter because he loved fiercely and lost, and routine became the only thing holding the grief in a manageable shape. The mailbox getting flattened is almost a perfect metaphor for the whole arc: something rigid and carefully maintained gets knocked over by life barging in next door, uninvited and a little chaotic, and it turns out to be the best thing that could've happened to him.
The cat is doing a lot of work in that story too, something else broken and unwanted that he can't help but take in, even while grumbling the entire time.
Did it hit you the way these stories tend to, that quiet gut-punch where you realize you're crying at a movie about a guy and a U-Haul?
It a film adaptation from a book by Backman, Fredrik (https://bookoutlet.com/author/backman-fredrik) A Man Named Ove, delightfully played by Tom Hanks and made me happy then a bit sad so to wrap it up, it was entertaining nevertheless.
That's exactly the rhythm and blues those stories run on, happy, then a bit sad, then somehow you land on entertaining anyway, because the sadness never overstays its welcome. Backman has a real gift for that balance: he lets you sit with the grief just long enough to feel it, then hands you a ridiculous cat or a botched U-Haul maneuver before it gets too heavy.
Tom Hanks does seem like an inspired choice for that role too, he's always been good at gruff-on-the-outside, wounded-on-the-inside, without tipping into sentimentality.
Good way to spend 2 hours or read the book and enjoy your leisure time.
