With shows like Mythbusters, Deadliest Catch, Dirty Jobs, Man vs. Wild, and Survivorman its hard to imagine Discovery doing a show that has absolutely no point; Which is exactly what "One Way Out" is, a show with no point.
"One Way Out" shows Jonathan Goodwin, an escapist, trying to get out of threatening situations. Sometimes he succeeds and other times he does not. While this show is very entertaining, it is not necessary. This show has a bit of a "Jackass" element but it does not go over the top the way that "Jackass" does and "One Way Out" is much more entertaining. Did I mention classier?
I wouldn't go out of my way to watch this program, but if you see that it is on I would definitely recommend giving it a watch.
