What we have here is a witty sci-fi teaser built around the coming wave of deep immersion gaming.

It's striking that eXistenZ, a send-up of computer games that parodied The Matrix avant la lettre, and one of the great underappreciated movies of the late 1990s, yields the richest trove of relics.

eXistenZ - both Allegra's latest beta release and David Cronenberg's dizzying B-movie - makes the different textures of game, film and life increasingly difficult to tease apart.

This pseudo-sequel to 'Videodrome' is arguably better than its predecessor.
