Gore can be used to great thematic effect. For example, the on-screen violence was one of the great qualities in Alien 3, IMO. The shot of the Alien after it kills Boggs and the blood sprays Golic.. the look of the alien was one of the best shots of the creature in the entire series. The way the alien picked apart some of the prisoners was intense (Jude being an example). I think that if done well, and I think the focus in Covenant seems to be on intensity, then it very well may be a good quality to have.
