It is perhaps impressive if you come from Canada where DTV never really caught on, but there's a dark side to the technology where stations carry multiple HD channels or more than six SD channels and it all looks (and sometimes sounds) like a bad dream.
Then there's the observation that all of these channels don't necessarily bring much in the way of variety or fresh content. In many cases, something that was once to die for leaves to make way for something else. The re-branding thing has gone on for too long.
