I thought the GM/Chevy ads were in very poor taste.........
My husband and I both thought most of the ads were in poor taste and were indeed violent. Fortunately, there were exceptions. We LOVED the blockbuster ad with the mouse. We laughed ourselves silly and talked about using our mouse at work today as we left the house, again laughing. Other honorable mentions that I can remember: Sprint (connectile dysfunction) and Justin Timberlake (who knew he had a sense of humor).
Much like their products.
