The well told is debateable depending on perspective, so that you can make up your own mind on viewing. (But if you really want an opionion on it; mine is this: they messed up the way to have done the series in the first episodes. Instead of a clear story, it was throw it all into cauldron and hope for the best outcome. Needed tightening up, which would have made the story much more clean and consistent.)
The visually impressive is definitely there, unless if you've got a good eye for noticing visual stuff; ie, if you can spot inconsistencies in videos and images easily, then the first few episodes of this series is horrible. There's quite a few things that doesn't sit well for anyone with a good eye. So in those cases, I would suggest you grab a lot of alchohol so you can be a bit bleary eyed so you don't notice as much of the issues as I did. Otherwise, it does look impressive (for a TV show).

Actually, I've just thought of an alternative way to get past the visual issues, you need a TV that's large enough where your eyes can't see the whole screen. So 55" at 1-2 feet distance, 65"+ at appropriate distances to prevent your eyes from being able to see everything. This can help viewers miss the issues talked about (as you lose perspective on the whole scene where the irregularities become noticeable from having a viewing reference point).

Oh, or watch on a really small screen so you can't tell the difference. Forgot about that one. Although I think most people are watching on their tele, so this is unlikely to happen. But an option still.
