It's almost impossible to believe that this film is from the self same Kevin Smith who wrote and directed Clerks. Gone is the biting wit and odd charm of that film, and in its place, big-budget pointlessness and a dozen more dick jokes. The many cameo appearances of characters from the other movies which comprise the extended 'New Jersey Trilogy' (Clerks, Mallrats, Chasing Amy and the woeful Dogma) serve only to remind the viewer just how good - or even average - Smith used to be. Indeed, whatever it was that made his work so individual and enjoyable was clearly lost some time ago.
Directorially, the 'post-modern' elements (several actors playing dual roles) are fairly well-handled, though presumably quite confusing for those who haven't seen earlier entries in the series. Unfortunately, however, Smith's usual lack of visual awareness and style is once more in evidence. In Clerks it didn't matter: the script was so tight that the primitive direction was irrelevant, but here, with hardly any gags hitting the mark (special mention for Mark Hamill's spectacularly unfunny cameo) it's extremely noticeable.
The acting too, is of a poor standard with too many lines and jokes fluffed, though Jason Mewes' usual one-note performance (essentially playing a toned-down version of himself, by all accounts) works well here. All in all, more puerile and less funny than its predecessors, though foul-mouthed children, stoners and idiots may take to it more than most.
