Legend of the Galactic Heroes (Ginga Eiyuu Densetsu) - best anime ever, so much depth, so many voice actors( holds a record i think), and so much classical music.
I second this. Hard.
A series that has 110 Episodes plus some movies plus gaiden shows and still manages to stay interesting all the fucking time, has so much depth[footnote] The basic story revolves not only around the nature and purpose of war but also explores issues such as value of democracy, morality of the soldier and generally the impact of politics on individuals.[/footnote] and such an incredibly epic feel to it that it is the very definition of brilliant. Also features an extremely large cast of mostly unstereotypical characters, trope deconstructions and exciting space battle scenes on top of it. That is why this Anime is by far the best space opera I have ever seen and not only ranks first on my personal list of favourite animes but also on my list of science fiction series in general. The only thing I could possibly hold against it is its sometimes glacial pace and the visuals which, especially during the earlier scenes, are just not on par with the stuff one is used to by now.
Now to some other brilliant series that come to mind:
[ul][li]
Monster: A japanese born doctor working in Germany saves a child in 1986. The child essentially becomes the devil and the doctor decides to correct his "error" and sets out to kill the "Monster". Psychologically ridden thriller that lives from shedding light on the monster's past, exploring the question of the nature of evil and what makes a man become a monster in the first place. Thoroughly eerie and creepy atmosphere and nothing but an highly interesting Aesop to boot. Has quite a few filler episodes so its pace is kind of slow, but it still is awfully interesting and cerebral. [/li][/ul]

Samurai X - Trust & Betrayal: Beautifully crafted Shakesperean tragedy about an assassin in the Meiji Era. Generally tackles the issues of redemption and responsibility. Haunting and highly symbolic visuals make it one of the most cathartic tragedies I have seen in an Anime. Maybe a bit short, maybe a bit too pretentious at times but after all: just brilliant. [/li][/ul]

Code Geass: The perfect mix between simultaneously having depth and just being an exciting action flick like Death Note. In contrast to the latter, however, this series manages to weave in some really interesting things into it's narrative ranging from the ideological difference between Lelouch and Suzaku (the former wanting to bring about change through a revolution, the latter through quietly changing the whole through it's institutions) and, of course, the whole character development of both during the course of the series, making for some really interesting character interactions and points to be seen in the series. Granted, it sometimes devolves into plain melodrama and some of the plot twists/ Mecha action sequences are just silly - still: exciting while deep and never fails to captivate me.

Spice & Wolf: The story of a growing romance between Lawrence, a traveling merchant, and Horo, an immortal deity who became obsolete during the centuries and who just wants to get back to her homeland. During their travels they increasingly fall in love with each other while they deal with adventures mostly focused on Lawrence economic activities. This series lives from the chemistry between the two characters, from their ongoing teasings, sarcasms and sillyness up until the point where Horo, in tears screams at Lawrence, asking "What am I to you?" in Season 2, brutally exposing the underlying tragedy of their impossible affection. And yet, despite what needs to happen at some point, the series emanates a feeling of almost remarkable optimism and joyful playfulness that always leaves me with a fuzzy feeling inside.[/li][/ul]

Fullmetal Alchemist (Original + Brotherhood) : What could I possibly say that others didn't have already? Where Code Geass takes the rollercoasterlike Death Note and beautifully fuses it with depth, FMA does that with a whole variety of other things. It does not only make for highly interesting points like the nature of science and the hybris of men, but also has exciting action sequences, dark plot twists, humor, character depth and a captivating story arc. It's remarkably idealistic despite it's very dark topics and it succeeds in providing a thoroughly satisfying narrative. This is also the reason why I personally like Brotherhood a shred better than the Original series, the storyline is much more developed and much more to the point than the original was.[/li][/ul]
Other animes that I could have included here: Higurashi - When They Cry , Cowboy Bebop, Princess Tutu (not finished yet), Paranoia Agent, The 12 Kingdoms and Hellsing Ultimate
