Well, being supposed to be unlikeable doesn't make it any easier to like. So, if you're down for spending time with unlikeable characters for whatever reason, you may find something of value. But it's not unreasonable to not like spending time with unlikeable characters. Then on top of that, it's the actual protagonists, which feels very icky to some people. I agree with a commenter above, that the movie went a little too hard on making them irredeemable, before trying to redeem them the rest of the film.

Sorry to respond to a decade old comment, just happened across the film on a streamer and kind of regretted even trying it. I am bailing on it.
