The original was expensive and complex, yes, but both of those things are fixable (modern technical stuff and Kong drivers, say).
It’s more that I’m not sure anyone would build a ride where the optics are that you’re trying to kill an animal any more (even Bruce). I never thought about it on the OG ride, as I’m sure no one else did because everyone just took it as read, but I was interested to hear during the 50th anniversary documentaries etc that the original film has a bit of a complicated history re the spate of animosity it started towards sharks and indeed a spell of quite widespread shark hunting for trophies / sport.
I’m sure some people will think ‘it’s just a ride’ but the simple question is when was the last time a ride plot was ‘let’s kill this thing’?
