I'm genuinely curious; what do you think about Knott's Scary Farm is declining? They've had some serious misfires, sure, but I wouldn't say the failure rate is somehow better or worse than HHN (and not even touching Six Flags, which had serious issues up until two years ago). If you take them at their face value where they replace two mazes every year and the scarezones are more or less unchanging features, I can't find too much reason to hate on them.
