These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Idiot Plot: Recording their conversations with their bosses right from the start would have solved a lot of the main characters' problems to varying degrees, but it takes them the entirety of the movie and a tip from a petty gangster wanna-be to figure that out. When they try it the normal way they're thwarted by their own constantly increasing stupidity.
The ironic thing is the recording actually would have worked, but Kurt choose to bail on the job to have sex with Harken's wife.
And two of them already had ample evidence to convict their bosses as it is. Julia had recorded evidence of herself molesting someone under anaesthetic, and Bobby wasn't exactly being discreet about his cocaine use.
Bobby crosses it so many times in his first scene as Kurt's boss.
Julia crosses it when she threatens to lie and tell his fiancee that he's a (false) sex offender.
Nightmare Fuel: Harken's murder of Bobby. It's the only scene in the movie that's not Played for Laughs, and it's surprisingly realistic. Not unexpected if you've been paying attention in the coming seconds, but still a bit of a shock when it comes.
