"Parasites" ate up my time

Why did I waste good money and three hours of my life to see the film Parasites?

• A couple of friends recommended it.
• It won the Palm D'Or at Cannes, 
• "Best foreign film in a decade" someone said.
• Justin Chang, critic for the LA Times, liked it.

Don't believe them.

This film is a blend of the Three Stooges and the Pardoner's Tale in Chaucer's Canterbury Tales.

The Pardoner's Tale is about three men who find gold by a tree, eat and get drunk, and all kill each other.  That's what the family of four in this film does.  Not everyone dies, but the plot is blindly predictable.  

So what if there's a subplot about a family in the basement?

So what if it contrasts wealth and poverty?  The characters are so unlikeable that it's hard to care when they start killing each other.   

I liked the foul four until they got greedy, which was about half an hour after the film began.  They connive to get others fired, take their jobs, and then get drunk and make a mess in their bosses' home.  Such pointless stupidity and selfishness makes me yawn and look for the exit. 

Somebody please explain to me why some of the culture's pacesetters liked it.
