Exactly. "Dropped the ball" means failing or screwing up. Again, YOU not liking something doesn't equate to a failure on their part. Not in the slightest.
If they had a huge marketing campaign and produced an overblown kiddy coaster (Alton Towers with Thirteen) - dropped the ball.
If they went for a totally untried and untested ride type with ridiculous downtime, coming in way over budget and ultimately losing them money - dropped the ball.
The biggest installation of a massively popular ride type with zero reliability issues - not dropping the ball.
See, you've correctly explained the definition of "dropped the ball", but you've completely dropped the ball on using it in any kind of correct context.
