You can't hate on Bill Spectre, the guy is a hard-working stalwart who clearly enjoys camping it up and entertaining punters with his excellent, panto-baritone voice and his penchant for ghoulish tales and magic (the winding finger trick was great).
I can't say anything positive that hasn't been said elsewhere, but I will say that there were a few weak moments that broke the third wall and sort of ruined the mood a bit.
My brother (a ghost walk afficienado) and I did the Halloween tour in 2012. During this set Mr. Spectre's phone went off which was pretty unprofessional. The worst part was that rather than make a joke of it, or link it to the story he was telling about the bell tower (which then also started chiming), he totally lost his thread and started mumbling to himself before attempting to actually take the call. That probably could have been handled a bit better.
Another moment, was Mr. Spectre asked us all to try and summon some spirits. Just at the climax of this routine, the wind began to blow heavily in the trees which made everyone a bit tense and nervous. Instead of exploiting this, Bill just seemed to ignore it and carry on with the less impressive planned "bit" he was doing. Again, it felt like a better showman would have made more of the fact his spirit summoning seemed to be working for real.
They are minor quibbles about what was an otherwise entertaining and unforgettable evening; I just think Bill can take it to the next level by improving his improvisational skills.
