Stan opening up his own restaurant seemed awfully random. Roger can pretty much take any situation and make it funny, but this didn't do much for me. Well, aside from the completely random cow birth cutting into the middle of a Stan/Roger argument and then both picking up right where they left off without missing a beat. Although that was one odd ending.
Steve's never-ending pursuit of sex is nothing new, but the new girl having an imaginary doll friend feels like another random plot point that they just pulled out of thin air. Though I did like the payoff with Steve leaving with his pants down.
Really liked this one, too. The B-plot was especially funny for its absurdity and Steve's commitment to the ridiculousness, if only to get sex. Fits right in with his desperate character. The main plot was fine, mostly for the food names that Stan came up with.
Finally, got to see the end last night after starting and stopping it on Monday. I liked the fact that Stan had an idea that worked which I thought was a nice change of pace. The doll/imaginary friend stuff was pretty damn clever.
I think the OH SHIT GOTCHA SUCKER ending is overdone and usually really annoying. But Illusionist was about illusory trickery and deception and so the whole movie was illusory trickery and deception. Under those circumstances I think it's appropriate.
