First up, looks like a lot of people are getting impatient in this forum... Let me just summarize some points and add a few of my own.
1) L lenses are premium grade Canon lenses: does not mean they are amazing, their specifications such as f spot number are usually small (i.e. aperture is large). Also, they use UD lense elements which creates less distortion
2) L lenses tend to have weather sealing: do note that not all L lenses are weather sealed

There are some good L lenses and other bad ones. From my own experience and from reviews on the net, Canon L lenses tend to excel in the medium to long telephoto, short lenses tend to have quite a few people complaining about CA and sharpness.
Each person would have his own idea of what is good or bad, but there are 3 things photographers tend to look at:
1) Sharpness: Most lenses are sharp in the centre but may lack sharpness in the corners.
2) Color: More accurate colors tend to be preferred. Chromatic abberation (fringing or pronounced colors at the edge of objects) are a big nono.
3) Distortion: Sometimes, you may notice that the photo 'bulges' up in the middle etc. This can be corrected using photoshop but a good lens tends not to have any such distortion.
Hope all these helps.
Stay fun and happy
