How would you like pretty, funny and entertaining (hypothetical) comedy show "Paedophile x family", glorifying paedophiles? I hope this metaphor explains what I hate about "Spy x family" which is anti-family spy glorification propaganda masquerading as entertainment.
Don't be deceived by likeable appearance: the show is about people who lie all the time to everybody, even to those close to them. And viewers are expected to be amused how clever protagonists lie and how well they conceal their secrets from everybody... This show excels in normalising deceit by showing dysfunctional family as cool and funny.
At no point in the show lying, theft, deceit and murder are morally unacceptable and those things are used (in abundance) without hesitation. Even the child lies...
Fake lives, fake careers, fake relationships, fake family -- anything goes for no good reason but abstract "world peace" which is an excuse for everything in this show.
In a sense, like most other spy shows, it is a blatant attempt to redefine immoral as morally acceptable, funny and cute. Which is disgusting in the essence, IMHO, also because of our willingness to accept such things, and even defend them, as long as they are funny enough. In other words, if propaganda of evil is entertaining, then it is "OK", right? Our culture have been weaponized to de-sensitise us to ugliness of spies and their inherent immorality.
Remember that spies are despicable deceptive state-sanctioned thieves and murderers employed by "governments" to do extra-judicial assassinations. Think not James Bond but "oh-so-funny" assassins of Skripals and Litvinenko... Why not make comedy shows about those actual spy scandals and see how "funny" that would be? While it is OK to laugh about evil, IMHO portrayal of evil as comedy is wrong. While Hollywood specialises in that kind of propaganda, it is disappointing to see when the same is done in the anime world.
The execution of the show is no doubt flawless, with nice visual appearance. Combination of suspense and comedy makes the show entertaining. Protagonists are likeable, confident, capable and creative at improvising. They face grotesque challenges and use any means necessary to accomplish their objectives, usually narrowly avoiding exposure. They maintain veneer of respectable public appearance but switch into "spy mode" without hesitation, with full commitment no matter how small is their challenge. Progression of the story is dynamic and lighthearted. It is an easily enjoyable show but it could have been so much more if it was not so shallow...
