Maybe give one of the old masters a chance, John Williams has sort of been pigeonholed with the grand, sweeping (and occasionally schmaltzy) scores in the last 20 years but he did write some great horror pieces.. Jaws of course but also The Fury etc, and he'd give it a more thematic approach like Goldsmith did and had a similar success with 60s sci fi TV series. James Newton Howard has some very decent material in his cv, often better than the films deserved. Goldenthal maybe deserves another look in too. I'd hesitate to say Howard Shore as I'm not a huge fan of his recent material, but his score for Cronenberg's remake of The Fly was good. As was Christopher Young's Fly 2 score (terrible film great music).
Just like to avoid the likes of John Powel (Jason Bourne), Zimmer on autopilot (Man of Steel) or the currently popular bunch who hammer out very generic scores (Desplat, Badelt etc).
