Pros:

• Discworld is amazing
• It’s like Tolkien but modern
• You will chuckle so hard you’ll have to have to have little breaks to breathe
• Small fandom so it’s easy to make friends & discuss things
• Really awesome if you like series because there are 40 books
• But there are actually 5+ series within that & several stand alone books so you don’t have to read all of them (although by the time you finish one series you might want to read all the rest)
• The world is flat & sits on four elephants who are for some reason standing on a giant turtle and I don’t think anyone is really sure why
• Easy to find a cool Discworld-related url
• Range of female characters (so you know the Joss Whedon Marvel/Steven Moffat syndrome of all the main females being kickass, skinny, kickass, perfect in everyway, kickass & pretty much the same character? that syndrome is stomped into the ground, cut up into tiny pieces & mocked)
• Canon lesbian characters
• Some super cute tv adaptions with cameos from sir pterry himself
• Deep shit reflecting on life the universe and everything, the rise and fall of political systems, the power of words, the prevalence of evil, the nature of humankind, human relationships and beliefs, and so, so much more
• Super silly bits where you’re like ye gods pratchett did you really just make that pun
• Ships ranging from teenage fluff to middle-aged fluff to damn hot af
• Characters who oppose their society’s gender binary (correction: their society’s gender…mono-ary? singulary?) & nice friendly badass werewolf woman lends them dresses
• Badass moments which make your insides do hoola hoops
• The fucking puns
• Really awesome large characters who either just don’t give a flying fuck or have to deal with fat shaming and prove that they are infinitely better, kinder, cleverer people than the fat shamers and often use their size to help them as they save lives/fight evil etc.
• There’s this book called Monstrous Regiment and it’s basically 400 pages of fucking up sexism, xenophobia and gender binary
• There’s a character named Adora Belle Dearheart and her partner (to clarify: she’s not his wife, he’s her husband) is called Moist what more do you want
• A Christmas/winter festival book which will leave you warm and happy and philosophically questioning
• Do you like funny footnotes?? So many funny footnotes
• Characters getting over & challenging internalised prejudices & beliefs
• Destruction of racial stereotypes 
• Characters call even the protagonist out on their assumption of roles which fit a white supremic system 
• Really good model of police/civilian relationship where the commander of police force fundamentally does not agree with the police/civilian model because "what was a policeman, if not a civilian with a uniform and a badge? once policemen stopped being civilians, the only other thing they could be was soldiers.” - or put more simply "a watchman is a civilian, you inbred streak of piss”
• young teenage witches coming to terms with their own strength & power, middle-aged witches who write cooking sex books and are as kind as can be, old witches who are canonically ace/aro spectrum and never regret that for a moment and just so fucking smart
• so many witches
• and there are wizards, and female wizards too
• Death is a character and he’s adorable and he really really likes cats and he has a granddaughter who looks after children and hits monsters with pokers and has amazing hair
• Super talented fandom who do art and fics which break your heart
• Very good realistic characters and protagonists which are far from perfect aka recovering alcoholic picked up out the gutter by a (6 foot) dwarf and a woman who is large and kind but perfectly capable of looking after herself and the recovering alcoholic and a garden full of swamp dragons - and the old witch? she is only a goodie because everyone else is too busy being bad - and there’s an ex con artist who spent his life ruining others’ bc he found it fun and is only now a ‘goodie’ because he’s being blackmailed - and the person in charge is a tyrant but he’s really a very reasonable one - and there’s a guy who literally just runs away from things the entire time I’m not even exaggerating that’s like the entire plot of his books he just runs away from things
• Have I mentioned the puns

Cons:

• There are no cons
• Discworld is amazing
• I will lend you the books
