I like them. They soak up queues from the coasters, pack a decent thrill into a small space, help areas deal with breakdowns (th13teen gets a massive queue if Rita goes down), and they look great at scarefest or fireworks. I know some people say it can make an area look like a fairground, but I think if they're themed well they enhance imerssion into the area.I'm really not *that* bothered about flats tbh. Coasters, water rides and dark rides are far more interesting to me.
And enterprise is still listed as a thrill ride on the queue time listing. Towers have relaxed it recently but it was pushed as a thrill ride not long ago.
