More conservative than her "other wedding" dress though.
Quite so. It's been a while since I've viewed this gem, but I'm confident that - despite the PG-13 rating - Marina wasn't even naked for her sex scene with Wil (and Shinzon ... and The Viceroy). There was simply no way we were ever going to see a Betazoid wedding, not even in the movies. Certainly not by this time! And for that ... yes, for that, I am deeply appreciative.
That wedding party scene was so segregated, Wesley Crusher was almost completely out of the movie.
Sure, it's kind of reflecting the way weddings are "staged" in real-life, the bride and groom and closest members tend to sit separately from everybody else at the reception, but as presented in the movie it just feels 'off' somehow because all of the white guys are in one part of the scene and all of the black guys are in another. I'm sure they could've found a better way to be inclusive of all the regular cast members (at the least).
You know, ever since 2002 there's always been something about the way this scene is staged that has bugged me. But it isn't until now I've realized what it is: exactly the above.
He clearly didn't have a touch for character based storytelling, certainly I recall him complaining bitterly about having to absorb the baggage of such already well-established characters, when all he really wanted was a clean slate. Nobody could have been a worse match for a feature based on The Next Generation, lest alone their final screen outing. Perhaps most telling was his complete removal of the ward room scene between Picard and Data, one of THE most crucial scenes in the telling of what these characters are going through in this story. Its like Baird went through the movie with a razor going "Ok guys, we're making an action movie here aren't we, rip the heart of it and do everything you can to de-emphasize character in favour of shooty bits and base emotion, got that? Get to work." 
Absolutely.
I'd never noticed before, but that railing behind the main cast in that second shot, to me, echoes the railing from the E-D. If true, that's kinda neat (even though they've been on the E-E for a while).
