Flavours you don't like in a cigar?

I smoked an AF Hemingway something or other (it was part of a massive sampler buy) on Friday. Great burn, lots of smoke, full bodied, spicy and leathery.. leathery.. hrmm..

I'm still a noob and discovering the flavours I enjoy in cigars, but I think I can put leather on the do-not-like list. The entire time I was smoking, I kept having visions of chewing on a 80's biker jacket. Though there were other flavours, leather was predominant, and spoiled the rest of the cigar flavours for me.

So what about you guys? What flavours don't you like?
