Quoting these posts from Steve after TTBAB closed:
I don't doubt people complained.
But I blame them for not knowing what they're going to and then making a big deal out of it when the show that was clearly trying to be scary ended up being scary. The signs were there. READ.
There's this weird thing that happens where any time Disney makes something that prompts a negative emotion people pretend it's a mistake instead of what they were trying to do. It's in all things they do (e.g. people whining that Bambi is sad), but especially the theme parks.
"Extra-TERROR-Estrial was scary!" Oh, ya don't say?
"Dinosaur scares kids!" Yeah, it scares adults, too, that's the point.
"It's Tough to Be A Bug was scary!" What, you mean the hornets weren't cuddly?
Like, they clearly made this things this way on purpose. No one thought having black widow spiders drop down from the ceiling was going to be funny. Being scared was the point. But that's just an unfathomable thing to some people, so we don't ever get to have anything but happy happy fun times now.
Imagine if they just never made rollercoasters because people constantly complained that they gave them a tickle feeling in their stomach and they didn't like that. That would be stupid; obviously don't go on the rollercoaster.
I've said it before in this thread, It's Tough to Be a Bug was not a personal favorite, I don't feel super sad knowing it's gone; it was good, but not irreplaceable. I can accept that's it's gone (though not a sucky replacement). But Disney's constant filing away of anything remotely scary? I can't get behind that and ITtBaB is a prime example.
