8. Heroes
Honestly, I feel like people expect this one to be on lists like this. The first season of Heroes was probably one of the greatest in television history, but the rest of the series just drifted by on fumes with hopes that people will still like it. Heroes ran for four seasons, the fourth being the one with the finale issue. Keeping the secret of people with powers is imperative and honestly, they really dropped the ball here. Having Claire climb up atop a circus ladder and then jumping off of the top, landing hard on the ground and repairing herself with her powers. On camera. REVEALING HERSELF AND THE EXISTENCE OF HER KIND TO THE WORLD! And then they just ended it there, as if nobody cared about what was going to happen now that the world has gotten wind about people with powers. I've tried to re-watch Heroes and I just can't because I know where it's going and that's not a place I want to be.
