It's not an excuse for a bad house....it's me giving you an option for it to not even exist in your mind.
And once again, "bad" is subjective. 8/9 isn't terrible. Hell, 6/9 isn't terrible.
Not everything is going to strike gold.
How many years have you gone to the event? Because for me, bad is Fear Factor, Disorientorium, Cold, Blind Terror, etc etc.
Bad is relative. Especially compared to the past.
