It's trying to be your typical build-to-a-cringe comedy, already seen in the likes of The Office, Peep Show, Extras, Partridge, The Inbetweeners etc. The difference is, those have plenty of chuckles along the way, whereas this has none at all.
Also, there's no subtle early build-up to the cringe in Whites. Last night with the Parkinsons-scene for example, it all came along a bit last minute and was predictable and not particularly amusing.
Whereas in the aforementioned comedies, they often stick many things in early on which don't make much sense until the cringe-worthy climax at the end. The wrist-band wasn't really sufficient tbh.
