I was just looking through Scarefest videos on YouTube, and came across the full length Trick or Treat Party show and in all honesty is looks like something you'd see in Butlins! It's certainly not fitting for Alton Towers. It's an okay show and well done to the entertainers that do their best to make it a bit more exciting. Although on the whole it's very boring and lacks a lot.
In Fountain Square or Cloud Cuckoo Land I think it would work brilliantly, but at the bottom of Towers Street it looks awful. On Towers Street I'd imagine something bigger and more exciting. The Trick or Treat stage is more suited to being in a smaller area.
It's a shame the original Trick or Treat format never stayed however. The witches back in 2010 were superb and made a lot of use of the stage. This show however does not fit well for me and I think they need to have a look at this in future.
Here's the video below for anyone that wants to watch the whole show.
