Sanford Harris
I love Fringe but the Sanford Harris storyline bothered me. I understand that there are a lot of crazy things in this show but my philosophy on that is I will buy a lot of the crazy stuff as long as they have the regular stuff valid.
In this case I do not see how anyone would put Harris in charge of the review of Fringe when the person that stopped his career was one of the main agents. There is a HUGE conflict of interest there. Again, I believe the Fringe science stuff basically because of how they handle a lot of the outside stuff.
Of course that is also why I was not a fan of season 5 but that is a different post.
