Although it's been a long time since I've seen Sour Grapes, the experience of seeing it- preferably alongside another Seinfeld fan- was fairly pleasant, in that biting Larry David tone. This was the only time David wrote and directed a film, and it does show that he's giving a good try to tell a story within the framework of a film feature all the way through. It's somehow quite an entertaining piece of quietly (or not so quietly) deranged satire on envy, sexual frustration, and the condition of a principle of something. The premise is simple- two good friends go out to Las Vegas to gamble, one friend asks the other for a quarter for a slot machine, and via the quarter in the slot machine the guy wins a helluva lot of money. By the friend with the original quarter's estimation, a part of that change is his, but the friend now says that it isn't. A likely Seinfeld sub-plot is stretched out so that the ideas are given a little breathing room, even if one recognizes that, perhaps, it would be a masterpiece if it were simply a Seinfeld episode, or more appropriately a Curb Your Enthusiasm with even more acidic humor and total unease thrown at the situation.
Around the premise, David also tosses in a supporting character who has one of his testicles removed- the wrong one by the doctor, who is one of the friends- and despite his now high voice (ho-ho) he seeks out some payback. That's one of the clearest big gags, as obvious as it is, is the moment when the 'testicle-man', as one might be tempted to describe him, is told by the doctor that the wrong one was taken out during surgery, to his immediate fainted response in a cut-away. On top of this, David experiments with some stupid sex humor (not that there wasn't at least a little later on on CYE, eg Jeff's mother's ass at a stoplight), like with Bierko's character in the self-humiliation of not being able to, um, 'service' himself in a certain way, under the stress of the tear in the friendship. As mentioned, none of this really makes for the kind of classic comedy one might expect, or crave, from maybe one of the only geniuses (yeah, I said it) working in comedy today. But as almost something of a fluke, it does its job well.
