This might be an unpopular opinion, but even though it's impractical (and sad

), I think they probably should change at least some of the theming, especially the stuff that's medical-related. I can see how the majority of its theming could be seen as morbid now, especially to those affected in the accident and their friends and families.
(I hope they don't change it though, because I love it. It's just very unfortunate...

)
Whatever happens, I think it should remain closed until the end of this season, or longer, depending on how long it will take them to fix any faults/make the ride safer.
