Me too. Clerks is one of the funniest movies I've ever seen, but Mallrats is boring, and full of annoying characters. I hate Jason Lee. I hate him in anything he's in. He acts like acting is just another word for shouting.
There aren't enough good one-liners, and compared to Dante and Randall, I couldn't give a toss about any of the people in Mallrats. I've not seen Chasing Amy, but I've heard it's not as good - which is why I haven't watched it yet.
