Okay, this reply is going to be to points raised in the past two in no particular order:
First, I'll reiterate that the situation w/the Romanovs is intended to be in keeping w/what is historically accurate/reasonable speculation, right up until the point that the main characters gatecrash their murder and whisk them away to Middle-Earth; another reason (aside from those I'll be mentioning below) is that though it is possible that Anastasia may actually have been lesbian or bi in real life, no indication of it or arguments arising from it have appeared in any diaries or letters from her family members.
Additionally, Anastasia coming to accept who she is ties together w/the 60's counterculture aspect, and wouldn't work if she had already. The Fellowship travels across a Middle-Earth that resembles the real-world late-60's, w/all the liberation that entails. The songs we've discussed are supposed to be but a selection of those Zoe, Jeff, and Dave play on the road, and Anastasia turns out to be a proper rock chick (which I can totally see happening; she reportedly wasn't much a fan of the operas they'd attend.) As part of this accepting of the "new" ways, she comes to accept her sexuality and feelings for Zoe (this is a week or two into the Quest.) She then faces opposition from her family when they find out, but love wins in the end.
Now anger at her parents and siblings clinging to the old ways may well certainly come up during that last part, but not to the extent you suggest; the whole point of Nicholas' arc is he's held up as a prophesized saviour come to take a throne and rid the land of "evil," and so re-embraces his role as absolute monarch in order to save his daughters. He's still clinging to the old ways, and this would include initially being horrified by his daughter coming out. In the end, though, he realizes the folly of these attitudes as the people of the land do away w/AM's in general, and come to accept the LGBT folk.
Santa Claus ("the Christmas Wizard") originally meets the Fellowship on the road in a parody of his appearance in Narnia. He then shows up at the end, when Saruman's Tower's been breached and a slapstick-heavy battle is raging; though the Romanovs have been pretty much swayed by Zoe and Anastasia's declaration of love, the bigots are still closing in, until Santa arrives and reiterates his point of peace and goodwill to all, all year round. The bigots accept this, and the LGBT folk, and all is well.
Of Tarantino's work I've only seen Inglorious Basterds; I kinda liked it, though haven't seen it in ages.
P.S. edubs31, I tried to respond to your message yesterday, but when I hit "post" it said that "The letters you typed don't match the letters that were shown in the picture." Is there a captcha of some sort? Because I can't see one; does anybody know how to sort this, please?
