I'm with James here. Chasing Amy is one of the most emotionally dynamic movies to come outta the 90s. Smith balanced the funny and the absurd with real feelings.
Those who expected bone-head dick jokes wall to wall would obviously be disappointed, but IMHO Chasing Amy is AS funny, if not MORE funny than the rest of his work. The context of heartbreak increases the humour, because it's a hella lot more tangible.
I find it hard to watch Chasing Amy and not be moved. I think those who generally don't like it come from a later period of Geek-Elitism when K. Smith began to change the tone of his movies. Coming off the back of Clerks and Mallrats I semi-hoped Chasing Amy would have more of the emotional edge that Clerks displayed on occasion. It's real film making folks, and it deserves credit, regardless of whether you wanted more dick jokes and pop-culture references.
