When I see something with a rating this high, I think that it must be one of the most groundbreaking and innovative shows in decades. That it must be something that's going to change the game and influence generations of television and film. I think of The Sopranos or something similar.
But this is literally nothing more than a formulaic, made for television police procedural. Apparently, David Tennant being in something makes it a "stunning masterpiece". I can't ever remember the public fawning over someone so average.
It's like viewers see a nice looking shot of scenery and think that because the scenery looks good, somehow the show must be good. That's not how it works. Don't get duped by slow motion and gimmicky camera tricks.
But, most importantly, there is nothing new here. Nothing innovative going on in this show. One can find a million murder mystery television episodes. Just because this is stretched into the multi-episode "netflix" format doesn't make it any different.
