Fifteen or so years on, Spaced remains one of my favourite sitcoms - for the perfectly observed characters and recreation of twentysomething life, for the razor-sharp dialogue, for the impeccable acting (particularly Julia Deakin as Marsha and Mark Heap as Brian), for Edgar Wright's signature style of direction (which felt creative and refreshing at the time, but irritating when it came to Scott Pilgrim Vs The World), for the wealth of subtle but knowing references, for not outstaying its welcome.
As Vice's oral history of the show reveals, though, the fact that only two series were made was more a consequence of fate rather than careful planning, and remains a source of regret for Simon Pegg. Nevertheless, the majority of the cast are right in saying that, given their ages, realistically it simply wouldn't work if they attempted to revive it. Much better instead just to revel in each and every one of the 14 precious existing episodes. As Wright says, "I'm very proud of what we did and I don't really want to spoil it now".
You should have listened to Jessica Stevenson and put in that Goonies reference, though, Simon...
