This. I'd be OK if it were just a sideplot with a prick neighbor, but come on. Random dude in a beach shirt blocking me in demanding my documents, or else? I'll take "or else", while calling the police and informing them about a twat posing as an officer. Illegal surveilance, too... I don't mind a "conflict in a sideplot" somewhere, but this feels like conflict for the sake of conflict, into which we're being railroaded. I don't know a single person who in that wouldn't go "Haha fuck off dude". And unfortunately it feels like this will be a big thing, considering that that's the note the epsiode ended on.
Plus seriously, always with the stereotypical bad man. Wouldn't it be cooler if the neighbor was, say, actually an upstanding guy with an asshole police officer wife?
