It's awfully tough to do horror on TV, especially broadcast TV. 'American Horror Story' wasn't really that scary; it just had a tremendous cast who generated a creepy vibe that made it fun. It will be interesting to see how they follow it up with this season's reboot. Other than O'Quinn, there's nobody really compelling on this show as the two new building managers are pretty bland, or more accurately, pretty and bland. I thought the guy who murdered for Durant to get his wife revived was an opportunity squandered - it all happened much too fast and if we had gotten a little more emotionally invested in them the inevitable outcome would have had more punch. We could have witnessed her decline over a couple of weeks and his sudden decision not to kill again didn't make a lot of sense given as how he agreed to it in the first place. Same with the concert violinist and his demise which opened the show (my wife was yelling "Keep running you dolt!"). And if an elevator had malfunctioned like that, it should have been more of a concern to the new building manager than it was. At a minimum, it would be shut down for awhile whilst the manufacturer went over it with a fine tooth comb. There would also be a hefty lawsuit coming. And so on....
Agree that if the overall arc is well-plotted it could be worthwhile, but I'm less enthusiastic about this show now that I've seen the opener. And I like Aleron Ives speculation above based on what we've seen so far.
