Around every action with a reason, there are an infinite number of pointless actions. By only doing things that have a point, we limit ourselves. So run the bizarrely credible teachings of Chris John Jackson, US motivational speaker and alter ego of actor Will Adamsdale.
At points, this Fringe first-timer's seminar is quite sublime. Like when he's trying to put his hand in two places, at the same time. Or when he tries to rhyme two words that don't sound alike. Pointless? Yes. But also, almost, profound.
Jackson is a brilliantly realised character. The way he speaks of himself in the third person, using his name like a brand, rings true. Likewise, his dramatic pauses and dynamic but meaningless terminology ("PTI - push through with intensity!"). The act is strongest as a satire on self-help credulity, so works best when Jackson's philosophy is at its most persuasive. In emotionally extreme states, he explains, we perform unreasonable actions. And for a second you think he's on to something.
The glimpses we're given of Jackson's mental frailty sometimes come at the expense of that credibility. And his more advanced teachings, in the second half, are less provocative. But Jackson is still an exciting new comic creation. If you seek freedom from the tyranny of reason - well, what better reason to see this show?
