One of my childhood favourites, this one. Although the film seems to want to make out that it is hilarious, that isn't the real reason I liked it so much. True, there are some subtle jokes but I don't think it was really mean't to be a major comedy. It is, in fact a light hearted cartoon/real life flick about a white blood cell (Chris Rock) and his fight against viruses and the like. I suppose I really just liked it because it was a good take on life inside the body (of Bill Murray) that is pretty fun and cute. I personally prefered the episodes as drix (the cold tablet) was hilarious but this is still well worth a look.
