I'd say you can measure how bad the season was this way:
Take what you thought was the worst new musical of last season and ask yourself, if it had opened this season would it have won any of the creative Tony's this year?
If the answer is yes, then it was a bad season.
This was a bad season.
There wasn't even anything enjoyably bad this year.
It was all so.....beige.
