Wool/Shift/Dust by Hugh Howey. A well written, immersive post apocalyptic fiction that has a satisfying conclusion.
The Passage/The Twelve/The City of Mirrors by Justin Cronin. Pretty much the same as above.
The Century Trilogy by Ken Follett. A huge read that spans almost a century (from just prior WW1 to the late 20th century), accompanying the same families from several different countries and embedding them into significant world events of the 20th century. Really well written and enjoyable.
I watched the first one on a ferry, and just hearing the title made me think it was going to be some nonsense. And then it was amazing.
Then they announced a second, and I was thinking what do they expect to do with this and then they gave something intensely heartwarming and heart wrenching. I found it better and deeper than the first.
And then the third. I don't think it was as clean as the other two, but it closed it off so beautifully I was bawling at the end. Absolutely perfect.
The Phoenix Wright trilogy--the first three original GBA games/DS re-releases. They set up and develop so many arcs that pay off both within each game and across the entire trilogy. I would even go so far as to say that Phoenix Wright 3 is one of the best visual novel games of all time.
And the story is only one of many great things! The game art is gorgeous and the soundtrack is full of bangers that serve their purpose well to complement the story.
Obviously, the Lord of the Rings Trilogy. Mainly movies for me because I haven't read them. Extended editions, obviously.
But also, I adore the mass effect trilogy. Yeah, the rpg elements get gradually watered down, and the third ones ending isn't the best, but it's still an absolutely amazing Trilogy that I replay yearly. And it all came out in 5 years! Nowadays, single games have 5 years of dev time, at least. In my eyes, it's as perfect as it can be....Once it's been modded a bit.
After watching the movies, I can't read the books any more. Tolkien was many things, he's great at world building and mythology, but storytelling is not among his greatest qualities.
So, I read the books. And they are very good. There is a reason that the series is so influential.
And there are definitely some things that I do not like about the movies. The shield-surfing, for example.
But as movie adaptations go, it is pretty darn faithful to the original. Like, I've seen a lot of movie adaptations where you're going to miss a lot of material if you don't do the books, but they kept all the significant stuff in. They streamlined it a little, and no Tom Bombadill, but I seriously think that it does a solid job of capturing the original.
Like, if there's any book or series where I think that watching the movie would get you a pretty good approximation of the material and still be a really good movie, Lord of the Rings has to be near the top.
The mass effect trilogy. Yeah, shut up, the ending is great. NEVER had a problem with it. It's a videogame, really expecting that the ending will take into account all the decisions over 100 hours of gameplay and dialogue and give you a very personal ending for you is lunacy. Even real life doesn't work like that. The 3 endings with slight variations depending of your war assets was more than enough for me.
If you mean The Hitchhiker's Guide to the Galaxy, man, I have a completely different take.
I use that as one of two prime examples of a series that I love the first book of but steadily like less-and-less as the series goes on. The other example is Dune.
Hitchhiker's Guide to the Galaxy starts out funny. Okay, yes, black humor, but it's funny. And it gets steadily less-pleasant and grimmer over the course of the series. I'm not really enjoying it towards the last book or so any more.
Maybe a third series would be the Calvin and Hobbes comics, though I don't know if you can call that a series. Late Calvin and Hobbes, if you've ever read through a complete compendium, is very rarely funny, just kind of unhappy and cynical. The early and mid stuff, by contrast, is my favorite comic.
EDIT: Well, at least Watterson did leave it on a positive note with the final comic:
I do have a pretty solid complaint about back to the Future part 2, because if Marty goes into the future he should arrive in a future where he disappeared back in 1985.
They really should have introduced a new protagonist just for that section, otherwise it's not internally consistent with itself.
Definitely not. I'm a huge fan of the originals since I was a kid, but there's no way Return of the Jedi finished out a perfect trilogy. No way. Not even close.
EDIT: It's by far my favorite, no other trilogy comes close for me. But it is not perfect.
It fully explains Wolverine's power set, explains why he has no memory in X-Men, and puts a pin in the storyline with Stryker by X2.
Folks HATE Origins, and I get it, nobody likes that version of Deadpool. That being said, it's NOT the shit show that Last Stand turned out to be, and with this trilogy, you can safely pretend Last Stand never existed.
The love story with Silverfox was sweet and touching.
The battle by battle history sequence with Wolverine and Sabertooth was great.
Even before the transformation, Ryan Reynolds nailed Wade's basic trait as "the Merc with the mouth" before it all goes horribly, horribly wrong.
The only thing it doesn't really explain is how Sabertooth apparently got brain damage between the two.
The Mistborn trilogy by Brandon Sanderson. The original one that is, the second trilogy in the same universe not as much.
A good example for a writer who managed to place two consecutive trilogies in the same universe is Trudi Canavan with the Black Magician & Traitor Spy trilogies.
The original Crash Bandicoot games for the PS1: while the 2nd is the best of them all IMO, the other titles are so good that they created out of nowhere one of the most revered PlayStation mascots
Not all their best songs on those two albums, and some of them kind of sucked tbh.
However. How the fuck ever.
Listen to the entire pair, all the way through, in order, longhand. I don't care, just do it.
When you get to the last track, Soldier side, it pulls together all the themes that have been foreshadowed and hinted at across two entire albums, and oh holy fucking shit. When it breaks, your jaw will drop.
