Romeo x Juliet
The original has the loss of the houses as a tragic event, whereas here the house system is demonised and R&J were intending to dissolve their houses of their own accord anyway. Kind of losing a bit of the impact there!
The overall moral the show seems to be trying to come across with is "place the importance of yourself over the importance of other people", which is on kind of shaky ground as far as morals are concerned. Although it does lead to arguably unpleasant consequences, so they may be trying to work against it, but if so they're doing it in a damn stupid way as people were following the opposite originally and need to be persuaded into acting otherwise.
Escallus & Ophelia needed to die in a fire. I cannot decide whether they are worse or better than Gankutsuou in Gankutsuou, but either way they occupy roughly the same position in the show. I don't believe they ever state exactly what the 'mortal sin' is aside from vague references about grafting things into Escallus, which doesn't shed any light on why that would be a mortal sin in the first place.
The ending is bizarre. So Juliet needs to be absorbed into Escallus in order to a) provide it nourishment so it can continue holding Neo Verona aloft and b) allow it to begin tormenting her for eternity as part of humankind's ongoing penance for the 'mortal sin'. Romeo eventually manages to convince her that this is not the best trade ever proposed, but Ophelia ends up forcing her into it anyway. After some fighting Romeo eventually manages to kill Ophelia and mostly kill Escallus, and get Juliet out, but he gets killed at the same time. This results in Juliet deciding to get absorbed into Escallus anyway because it would be a shame for the world to be destroyed when it could produce people like Romeo. Then Neo Verona lands in the ocean.
So our final score is:
Romeo dead after saving Juliet from an eternity of torment.
Juliet in an eternity of torment after saving Neo Verona from falling to its doom. An eternity of torment while hugging dead!Romeo, might I add.
Neo Verona no longer aloft.
The only winner here is Escallus, although as it can only eat Capulet girls for no explained reason (perhaps it was a Capulet behind the 'mortal sin' originally?) and there are now no Capulet girls left, it will die in a couple of generations anyway (unless Tybalt has daughters, but he may not count). HOORAY!!!!!?!?
But at least Romeo & Juliet died. It was looking there for a while like they wouldn't.
Gundam 00 v6
A large amount of named people died, which surely must have appeased the purists that go on about how large amounts of named people need to die in Gundam endgames and the amount in GSD just didn't cut it, setting aside 0079, 0083, Wing, and SEED. Although some of the dead people showed up in the SS teasers, which must have put a damper on their day.
The Alvatore kind of comes out of nowhere, which is a little disappointing. Is it something that they had put together as per the Thrones or something that was left at the base or what.
Only two thirds of a particular group died, and they left one of the annoying ones alive. Tsk.
A certain fellow showed up for no apparent reason, completely off his rocker. Or so I thought at the time, but I was told that he was actually insane the whole time but never really in a situation where it showed. I can sort of see that, but I dunno. It was a fairly disappointing end to him anyway.
Will that guy and that girl get into a wacky situation in SS where they have to fight each other unknowingly!? It would not surprise me in the slightest but SS still doesn't seem to have a start-being-released date yet.
All up it was fairly good. They dispelled a bunch of mysteries but replaced them with new ones. Looking forward to SS.
