Query: Not very sharp

I've heard great things about this lens so I spent the $$$ on it. To my disappointment it wasn't very sharp. I'm not sure if I had a bad lens or what but I would think spending that much money it whould at least be a little sharp. I posted a few orginals on some photography sites and the most comments I got was "its very soft" and "not very sharp". I'm a die hard Canon person but I'll have to say that I'm not very happy with this lens.
