Many reviewers have criticised the combat, the repetition, a smattering of trial-and-error moments. There has been a general compulsion to counter the sequences of innovative genius with niggling doubts about core mechanics. This is frustrating and I think it highlights one of the key issues of contemporary gaming – what exactly is a videogame and what are the fundamental elements every game must provide? Because, if it were a movie, Mirror's Edge would be critically lauded by the specialist film press – it would be considered a forward-thinking masterpiece. Sure, it's dangerous to compare two such different media, but there are key similarities – one is the way in which critics should be able to deconstruct the experience on offer and draw from it undeniable values that outweigh concerns about basic construction.
