McLennan is upbeat to the point of being irritating and unprofessional while McCartney is more realistic, but frequently tactless and socially awkward.
The show is run on a shoestring budget, funded by commercial sponsors who manufacture and market questionable products.
The production crew are either under-trained or employed as part of a prison work release programme, the show is constantly beset by technical problems, and the guests are unqualified "experts".
McCartney and McLennan attempt to remain enthusiastic, but inadvertently reveal dysfunctional and sociopathic behaviour as things go wrong.
The last episode of the second series of Get Krack!n, featuring Miranda Tapsell and Nakkiah Lui and co-written by Lui, trended on Twitter, and was widely lauded as hilarious, ground-breaking, hard-hitting satire.
