The BvS "wins" are all deserved IMO (except for Worst Screen Combo, Affleck shouldn't get roped into another Razzie win; his Batman/Bruce was easily the only consistently good thing in the film). Easily the worst film I saw last year.
Haven't seen Hillary's America but some of the reviews I've seen about it paint as absolutely terrible, so I have no feelings about the awards it got (including Worst Picture) one way or the other.
Haven't seen Suicide Squad yet, but based on everything I've heard about it; damn did it evade Razzie nominations like a bandit. Surprised it wasn't even up for Worst Picture or Worst Screenplay.
