People who give Charlie Bear one star just don't understand what it is (or atleast want judge it for what it is instead of understand it).
Before going to Charlie Bear, ask yourself - do you want to get laid? Not in a maybe have a nice conversation, talk about the difference between Aristotle and Plato, or just plain, raw and dirty, dance with a girl and get laid?
Before going to Charlie Bear, ask yourself - do you want to grind with a not-altogether-wholesome-person-with-Daddy-issues? Not sympathize or develop a repoire, but GRIND.
Finally, ask yourself, do you want to drink shots with 90% vodka, 10% cocktail mix added in for pure effect and the point of the shot is SIMPLY to get you wasted? Not discuss the ability to taste the HOPS in one beer over the other.
If your answers are YES, then Charlie Bear is for you. If not, then go peddle your I'm-too-nerdy-and-advanced-for-popular-music-and-Âdirty-dancing routine elsewhere. I'm just as smart as you (I'm a year away from being an MD), and yet I love Charlie Bear.
No, I don't go to Charlie Bear for conversation or to try good food and drinks. I go there because the crowd is wild, the music is loud, the dancing is obnoxious, and the people just want to have a fun, sexually-explicit time. Does that make me or anyone else a whore? NO. We just want to go out, meet people, dance to loud music, drink vodka and develop some stories. Charlie Bear is  the prelude to The Hangover, and every other film that circulates around loose morals and quick drinking.
If you can get over the obvious misgivings of Charlie Bear, then you may truly appreciate it for what it is. And yeah, I do believe Hemingway would have rocked out to the best of them at Charlie Bear in our day and age.
