I've been on IMDb for quite sometime now, but have yet to feel compelled to write a comment. I suppose my biggest concern is that one of my favorite shows (i.e. Freaks & Geeks, The Class, Undeclared, etc.) will again meet its' demise if not for full and utter fan support.
Right out of the gate, this show grabs you with not necessarily likable characters, but real characters. It makes no excuses for the way people act or the situations life inevitably holds for us on a daily basis. It is not over-dramatized, watered-down or needlessly careful. It's appeal is rather than being presented as a miniseries, it is shot more in the tradition of a motion picture or cable series (not unlike The Wire -- best show EVER) where measures are taken after the shoot to make it prime time friendly without being corny or sappy.
Though it's too early in the game to give this a 10, I can say that if you haven't checked this out yet, do yourself a favor -- you won't be disappointed.
