I'm braced for not great either, but I will have to give them some credit for working their butt off. Trick 'r Treat has gone up insanely fast.
And while I'm sure many haunt fanatics will find many faults (which will very likely be justifiable), I do suspect that the average park guest could find it a good value. Even at the higher price. Between that, and the fact that there's now a chaperone policy, I suspect it won't be nearly as crowded, which means you could possibly get a LOT done both in terms of mazes as well as rides.
I've said it before, and I'll say it again... while I definitely prefer higher production value, it's not a requirement to have a good scare and a good time. If I just had a single night at a park, I'd rather experience a lot of lower quality production mazes than a few high quality ones.
One of the most memorable mazes I've ever done was Nightmares at Clifton Hill. And it's basically a maze in pitch blackness, with zero set design at all (well, visible set design, anyway). On the flip side, my next favorite was Mysterious Mansion in Gaitlinburg, which is highly themed. So either can be effective, if the cast can pull it off.
