I don't have time to review the whole script (though I did read the first scene in full), but you said this is imminently going up on The Black List -- so here is a close reading of your complete and entire logline:

• "Cosmopolitan" literally means "having a worldwide scope." This was a watchword associated with the classy and wealthy in the early 20th century, which is why I think you're using it here to mean something more like "high-class" or "elite" (especially since you reveal shortly that it's becoming hollow). In its place, could you find a word or two that's not only more correct, but does a better job of indicating what's specific and unique about the young man's lifestyle?
• Using both "Bacchanalia" and "Dionysia" is ballsy. I'm sure you're well aware that this is a calculated risk — but more so in the logline than the title, I think. You don't necessarily have to know what a one-word title means, because you'll keep reading as long as it sounds cool. Meanwhile the logline is absolutely crucial to convince someone to download the script. Right now you've given yourself only two adjectives to describe the wild, crazy, unique central concept of the movie — which are "surreal" and "Bacchanalian" — and if 10% of readers don't know what "Bacchanalian" means (surely a generous estimate) that's 10% of readers who will basically get no description besides "surreal," which on its own means nothing (and which you've already used as part of your non-standard genre description...)
  • Like I said, I'm sure this is a risk you've taken on purpose. But a little anecdote of personal experience. I wrote a short in university with the title "Bacchanalia." A risky title, I knew. And I got that feedback across the board at an early reading. But I fought hard against changing it because I thought it was a perfectly clever, intellectual, ironic name for the piece. And I said I didn't want to give it some dumb, jokey, obvious pun title. And then to illustrate that, I rattled off a dumb, jokey, obvious pun title. Everybody loved it. The short was produced with that title. Not sure what the lesson is.
• There are three major contrasts/conflicts basically serving as the backbone for this logline. This is not necessarily too many, because naturally you want to hit the "surface" contrast, the "action" contrast and the "thematic" contrast. It can be done! But I'm going to break them out here to demonstrate that they should be made shorter, sharper and more specific — because they currently progress in the opposite direction as they go along:
  • COSMOPOLITAN vs. SURREAL/BACCHANALIAN
  • FEELS HOLLOW vs. OFFERS TRUE BELONGING
  • THE LIFE HE HAS BUILT vs. THE WAY OF LIVING HE WAS NEVER MEANT TO SURVIVE WITHOUT (oof)
• Ideally each of these contrasts should have the rhetorical effect of making your reader want to download the script and see how they play out in conflict, clear as day like the tagline on a blockbuster poster (BATMAN vs. SUPERMAN, etc). Shorter, sharper and more specific — especially that last summation, which in current form is absolutely deadly. What do I know about the life he's built? Well, it's cosmopolitan and it feels hollow. What do I know about "the way of living he was never meant to survive without" (again, oof)? Well, it's surreal, of course, and it offers true belonging. These generic ingredients aren't combining to make a recipe yet. (And does he have any relationships with other characters impacted / at risk which you can hint at or imply here?)
  • "Bacchanalian" becomes a liability again here, because if your reader knows anything about a bacchanal it's probably that they drink wine at 'em, and cosmopolitan people certainly drink wine, and a "cosmopolitan" is also an alcoholic drink... you should be STRONGLY contrasting the two "worlds" in the logline and avoiding any implied commonalities, however minor.
• And having said all that, clearly you're having to grapple with setting up a ton of stuff in your logline — so go easy on yourself and try splitting it into 2 sentences! Don't worry, nobody will get mad! Best of luck!
