Never heard of it.
[post will include a lot of my religious preferences, which are Christian as I would probably not include it on most other forums, in case it could bother people but I will put that in a diff color text.]
It is my favorite work of fiction, actually, and it does deal with a lot of taboo subjects and implied homosexuality, I still think it's something that is highly intellectual and has themes I can appreciate as a Christian and as a human being (most of the taboo is veiled and a lot of what is suspect helps emphasize what kind of world Ohtori is. Nothing graphic and not really vulgar visual wise or language). I highly recommend the anime series. The movie is not really my cup of tea because it tries to cover too much material in such a short time span and is really out there. If you have a problem with homosexuality, the movie might bug you (I don't have a problem, I even ship Utena and Anthy more than any fictional pairing, but I am just saying).
Haven't read the manga.
But it is fascinating on many levels. Do check it out. It intertwines a lot of biblical allegory and unintentional allegory.
[spoilers from a Christian perspective]
I first saw the anime about a year ago and fell in love with it. It was a year after I had a falling out with my faith and the ending of the anime admittedly stung at my heart with the possible religious allegory of dying to save another (i.e. crucifixion, even the swords look like nails when they are about to drive into Utena). It was the sort of love I associated with Christ's love and it suddenly became so real to me and convicted me of a very legalistic though devout faith I had a few years prior.
I connect a lot of the themes with my faith and think Utena is a very good role-model to emulate (when she's doing the right thing and not sleeping with a guy who represents Lucifer...but we all have been guilty of that on an allegorical level).
The symbolism is extremely deep and I see a lot of allegories and a lot of themes that would take many threads to talk about.
But on a personal level, I see Ohtori as being symbolic of the world (in the biblical sense), Akio as what he is meant to represent, and Dios as what he is meant to represent. I see Utena as conquering through her own faith and nobility (akin to righteousness motivated out of a selfless love for Anthy). Even the concept of being in coffins and operating under delusion makes me think of the theme of Christ lifting us from our coffins (what Dios did and what Utena did), bearing our sins and suffering (Utena's sacrifice).
I find it interesting that Utena wins every duel almost by channeling Dios' spirit as a vessel. Sound familiar? Yeah. It's called having the Power of Dios.
I don't really think the creators had a particular faith too much in mind when creating the series, but the symbols are striking and do draw on Judeo-Christian concepts. Such as being baptised before ascending to the duel arena.

[still spoilers]
From a general perspective, I think the interpretations are just so vast and I like examining it from a myriad of possibilities (not just religious, but it's sometimes fun to discuss it)
Some of the symbols are pretty obvious, car = adult power, for instance.
I do think main canon themes really are the shedding off of childhood but not submitting to corruption associated with adult hood. After all, for Utena to graduate from the school (and becoming an adult) she has to abandon her childish delusions of finding a prince to live happily ever after with and make a real sacrifice, a very adult like thing to do and a very adult decision. Even Akio, the 'real adult' is not able to sacrifice himself for another (adulthood is about sacrifices, such as if you want a family...sacrifice) and is confined to the school which prevents anyone from growing up. So it is about maturity. It is about defying boundaries and roles and 'stripping down to nothing' to be oneself. It's about abandoning scripted roles such as being the Rose Bride, the Princess, or the Prince. In the end, I believe, Utena is free to be Utena in the outside world and Anthy is free to be Anthy. I find immense value in that, personally, and it has been even inspirational for how I approach my own faith, now, after having in the past killed the purity of it by trying so hard to be something I was not and to forget it's about love. And I think the love between Utena and Anthy (whether we want to call it friendship or more makes little difference to me) is a fine example of how love is...forgiveness, selflessness, sacrifice, compassion, etc.
Regardless of how you see it, I think an important element is being true to yourself and also doing the right thing out of a sense of love. And that seems to be true nobility and the key to being free.
For people who really want to dig deeply into the series, I recommend Empty Movement: Your daily dose of Shoujo Kakumei Utena! As it has just about everything there.
I have written a number of essays and musings on the series, myself, including links to Christianity and Buddhism (as the protagonist can be potentially seen as a Christ figure and a Siddhartha figure).
But what I like is that there are so many symbols and allegories and meanings intertwined that it really is something you could study on a college level as if it were a book.
