I don't think any bikes are "bad." Hybrids get no respect because they incorporate so many compromises. Consequently, they are too fragile and inconvenient for errands and commuting, have the wrong tires for off-road, are too heavy and non-aerodynamic for road riding, and so on. However, although they don't do anything particularly well, they can do everything. That's why they are the "default bike" that an LBS will try to sell you if you have no clear idea what riding you will do. My back-up bike is a hybrid, and I enjoy riding it. That's enough for me.
