There's a way to a make a bad movie and make it enjoyable in a "so bad it's good" kind of way. And that's to hire incompetent people for everything and then have the bad actors give it their all. It's been done so often most notably with Tommy Wiseau's first movie, "The Room". It's been called the "Citizen Kane" of bad movies and that's a title that genuinely fits. Everything about that movie is wrong but out of it grew this incredible movie that really needs to be seen to be believed. Tommy intended this to be a serious drama but because he heard people were laughing at all the serious moments, he decided to change his tune and say it was always intended as a black comedy. He even wrote that as the tagline for it.
But this comes with a problem. People expected badness from Tommy so that's what he gave them but you can't do the same thing on purpose. It has the stink of artifice on it. What was charming in the first movie becomes painfully obvious in everything he does afterwards. Look at the original "Birdemic". Then look at the sequel. The actors are in on the joke and it shows. What made the original so great is the bad everything. What made the second so bad is they tried to imitate the first one. And that's where we are with "The Neighbors".
The actors, including Tommy, are intentionally giving a bad performance. They're overacting because that worked in "The Room". But now you see them deliberately trying to do poorly. It's no longer "so bad it's good". It's "so bad because it's bad".
