This show is dear to so many people and I finally understand, it's a subtle, unassuming comedic masterpiece that executes the jokes and the interactions fantastically. The characters are very believable and what makes this show a hilarious legend is the humour in observing social behaviour. True to being an American show, it wraps up in a heartfelt way that's very satisfying to watch (despite a few injustices).
The humour is hard to pick up on initially, and it takes a couple episodes into season 2 to get the rhythm of the characters and to fully laugh out loud. After that, you get to appreciate the ignorant yet sweet nature of the world's best boss, and the everyday antics at Dunder Mifflin. You'll fall in love with the characters and throughout the series will have both rooted for and disliked each of them, which is a sign of how complex they are.
(mild spoiler alert) The show had 2 mains that had to leave the show either temporarily or permanently, and this has been done 3 times throughout the series. The first 2 times were written fairly smoothly into the plot, but the last one was kind of out there and left me shrugging and saying... ok then. That character deserved much better. Honestly, season 7 and season 8 could have been done a little better; after Michael left, it was evident that the show was struggling to use magnified comedic traits of the DM employees for laughs, but it wasn't working superbly, and there were some strange, out of place characters added into the story. Some episodes of season 8 were downright difficult to watch and left a bitter afterbirth. The show simply wasn't effective after Michael left, but it still powered through to finish the plot, which I appreciate.
Though the show had its falls and perils, it's still the most quotable and memorable show I've ever watched. This might just be the show that defined humour in the 21st century.
