Not at all. I use 'em a lot. And I recommend anyone inside of 20 miles from a transmitter at least give 'em a shot. "Start cheap and keep receipts." That's my motto. Wallyworld will take em back if they don't work.
Thing with ATSC reception is, it's all or nothing. Any multipath can cause a loss of picture. With analog, someone walking through the room or a plane flying overhead might ghost the picture temporarily, but with digital, the picture could go away, entirely. And many people might be in places where one or more stations require adjustments to the ears to optimize the signal for minimum picture dropouts. That can be maddening. Easier to just hang some more aluminum so the signal quality is always adequate.
Walking the fine line between jaw-dropping and a plain ol' yawn.
