I also think it's a very funny movie, but if Cronenberg's sense of humor doesn't typically work for you, you might have a tough time sitting through this one. It really breezes by, though, and I have seen some middling reviews state they wish it was longer and that some things were more fleshed out... but like Cronenberg's other films, he kind of gets in there, hits his points with panache and some cool visual moments here and there, and then gets out while the budget still allows. I don't know if anything really necessary is missing from this movie, it just sets up such an interesting and involved world in about a hour and a half while the narrative plays out and then suddenly it's done. You almost feel like you're waiting for that "Next Episode" button to appear in the lower right. But I don't think that's a bad thing. Some movies can leave you wanting in a good way.
It's a movie I'd hesitate to recommend to most people but it was so far up my own alley it's hard for me not to talk about it in a positive way.
