Nobody wants to grow up, not when they're young. All that responsibility, the boring clothes and the pressure to get a 'proper' job? No thanks. It marks an end to tantrums and being the favourite and being silly. No wonder that Brennan Reece is feeling conflicted if this is what 'growing up' means.
Clearly it's not what it means, but Reece's reticence to join the adult world seems genuine. His list of forbidden activities in adulthood paints it as dark and drudging as the Ministry of Magic after Voldemort's arrival. Reece is buoyant and enthusiastic, which carries the show when the gags miss their targets – something that happens at regular points throughout the show.
There are times when Reece comes across as a bit of a spoilt brat, clammering for his mother's attention after the arrival of his newborn nephew. But for the most part he is a likeable, hyperactive young man arguing with himself over what it might mean to grow up and how much he could lose in his surrender to it. He is conflicted, and with this his direction is muddied along with the strength of the show.
It's not new, but his audience interaction is charming and cheeky, and Reece himself is really rather sweet.
