How old were these kids supposed to be?
The average age of the group appears to be around 25 years (Max looking even older and Ira looking a bit younger), yet they were oddly concerned about some very... high-school (if not middle-school) type of issues. Worrying about parental punishment from drinking "marked" bottles of liquor? That struck me as especially strange. Can't they just buy their own booze? Even if just to replace/refill any bottles "borrowed" from their parents. They're shown drinking at the bar in the beginning, and the gambling in Atlantic City would suggest they're all at least 21, or at minimum have good enough fake IDs.
I know it's a pretty trivial complaint considering the ridiculousness of their whole plan and the movie in general, but was just curious what their age is actually supposed to be. Several of the kids seemed to be deathly afraid of their parents, yet didn't flinch when it came to kidnapping and mutilating a deadly mob boss, on the off chance that he would have the ability (and willingness) to help them out, even after these transgressions against him.
I guess some might argue this element adds to the dark humor the film was aiming for--and if the execution was better it might have worked to a degree. But in this case, it mostly just struck me as poor writing.
