Mine is quite good. As indicated in the first reply, 28mm is not very wide, unless one is using a "full-frame" DSLR or 35mm film. Your camera has what is termed a "cropped-frame" sensor. Teamed with a 10-22mm EF-S lens, I found the 28-135mm useful with 40D and 7D cameras. Now that I have a 5D, the 28-135mm is better able to serve as the only zoom lens for a day of walking about with just one zoom lens.
You may want to consider a zoom that starts in the 15mm to 18mm range at the wide end. I was handed an 18-135mm lens to test a 7D at a camera shop, and really liked my brief experience with it.
Do see the reviews of various zoom lenses in the Reviews section of Cameralabs!
