Long post alert! And likely off topic.
I didn't like Alex at first but as the member above me says, he and Charlotte kind of share similar expressions sometimes. Early photos of him make people react negatively towards him. But lately I've seen that he and Charlotte have similar...i don't know how i should put it but perhaps 'aura' or 'vibe' would be the closest words i can think of.
People sometimes complain about the Casiraghis acting like private citizens and not as representatives of the Principality and I'm not surprised by the sort of reaction people also sometimes have for the boyfriend and girlfriends of the trio. The Casiraghis have always been in that strange position of pseudo-royals-- semi-private citizens from whom people expect too much because of their privileged upbringing, good looks and fascinating bloodline. Add to that the fact that they could well inherit Monaco someday since the heir is childless (yet) and it makes for an uncomfortable position of 'are we it or are we not it?' Meanwhile the Casiraghis have chosen people from their own very close-knit circle of intensely rich, intensely private friends and now these kids are also in the lime light. I simply don't think the bf and gfs, especially in the beginning, automatically know how to deal with public attention. At any given day, some of us probably look indolent without knowing it, or lick our fingers while eating in public (I'm talking about boys, lol) but luckily we don't have cameras waiting to shoot and capture such moments and people reading all sorts of things into your gestures and facial expressions.
At any rate, I like Beatrice most which I think is because she translates so well in photos, Alex next then Tatiana. But Alex is the one I'd like to have a conversation with, among the three. His interviews are cool, his interests are accessible but intellectual enough and I like what he's done with 20 Hoxton Square. In a way, I get what Charlotte sees in the guy. So can she do better? Probably. But she can do worse too.
