Yep. A non-family coaster has a limited rider base compared to most Disney rides (see Guardians, which is relatively easy to get on even as a brand new attraction featuring a popular IP), and the fact that it's so short exacerbates the issue.
It's obviously better than adding nothing -- no argument there. But it was one of the worst options for adding needed capacity to the MK. The Main Street Theater would have been a much better use of money.
I hear you , but personally I think it’s gonna pull people away from the mountains (you know - the ones with the longest waits) - this is what MK needs. God the last thing in the world we need is a theater playing Disney movies , live entertainment seems to be a dubious proposition as well with current management
