Now ladies and gentlemen, it's unbelievable to read but I haven't watched a single Studio Ghibli movie yet but plan to do so in the next time. Since there's such a huge range of films to choose from, though, I don't know which ones to pick. Could someone recommend me the best ones (the must-watch ones, so to speak)?
Um…most of them. I'll break it down into a few categories, sticking primarily with the Miyazaki films, which I prefer and am most familiar with:
[disclaimer: I recommend watching all of these in the original Japanese with subtitles, though some of the dubs are at least adequate]
The Accessible Ones:
My Neighbor Totoro: Probably the best place to start to understand Ghibli/Miyazaki. The storyline is relatively devoid of conflict, but the characters are lovable (the father is especially an underrated character in the Ghibli canon), and Totoro and Catbus are essentially the core of the Ghibli world. Laputa: Castle in the Sky: For a long time, my favorite movie, and still up there. Lovable main characters, a fairly tight narrative (that has some minor issues in that last bit), and has the scope of a classic adventure. Also, lots of flying and robots.
Porco Rosso: In my opinion, Miyazaki's most complete film. Superficially it's a little odd to be in this category–it's about a man who happens to be a pig flying a plane in post-World War I Italy--but the story is among his best and most coherent and the movie concludes wonderfully. Plus more flying. Miyazaki loves flying.
Castle of Cagliostro: Caveat here: the accessibility of this one requires some small familiarity with Lupin III, which can be attained just by looking at the wikipedia if you're new to the series as I was when I first saw it. Once that's out of the way, this is one of the most entertaining films ever made. So many of the setpieces in the film still fill me with a childish glee. Add in the fact that he converted Lupin into a lovable thief with a heart of gold and it's amazing stuff.
All four of these movies are or have been at some point in contention for my all-time favorite movie.
Less Accessible Masterpieces:
Spirited Away: The story on this one can be downright random, some of the characters are odd and unsettling, but it creates an absolutely amazing world that's unforgettable. I also think it has Joe Hisaishi's best soundtrack (Hisaishi was the John Williams to Miyazaki's Spielburg). There's a scene in a train at the end that never fails to give me chills. This one might be better served after checking out some of the others, but it's definitely worth seeing.
Princess Mononoke: I'm still not entirely sure what the hell is going on at the end of this movie, but the getting there is amazing. Another fully-realized and unsettling world with another fantastic soundtrack. This is possibly Miyazaki's most adult movie, but it's still get the sense of childlike wonder of all his other films.
The Slice of Life Movies:
Whisper of the Heart: Not technically a Miyazaki film, but his fingerprints are on this more than some of the other non-Miyazaki Ghibli films (the director was intended to be one of his successors but died after the release of this movie). Might be the deepest movie thematically of his works and has some fantastic scenes involving, of all things, John Denver's Country Roads. I'd wait on this one if you're trying to get a sense of Ghibli, since I connect the studio more to fantasy worlds and settings and this one has almost none of that.
Kiki's Delivery Service: Truly a lovely little movie, but there's almost no conflict, the story intentionally meanders, and the world isn't quite as interesting. This, Totoro, and Ponyo are probably the movies best suited for a young audience.
Flawed but Good:
Nausicaa of the Valley of the Wind: This isn't a bad movie, but it's a reduction of Miyazaki's masterwork manga and thus has the baggage of being a pale imitation. Also makes some odd decisions in story. It does feature his most fully-realized world, though. Avoid the cut-and-dubbed disaster released under the name Warriors of the Wind, though, oddly enough, that was the first anime I ever saw and what got me into it.
Howl's Moving Castle: Story is all over the place as are the characters, but some of the scenes are oddly moving and the castle itself is fantastic. Probably the weakest of his movies. Oh, wait.
Just Don't:
Ponyo: I hate this movie. (All right, all right, some people love it, but the central conflict and ending make no sense to me and the main character isn't as immediately likable as all of his other characters.
