Agreeing with the others. I think you plan to open only the gift they give you at his home and the gifts LordL gives you if you don't exchange presents with each other at a different time. When DH and I were dating/engaged his parents were very sweet. But on Christmas morning at his home, I'd open a single lovely present (unfortunately, it was usually a perfume I didn't wear) from his parents while DH, his sister, and his brother opened 5 or 6 gifts each. (DH and I would exchange gifts earlier in the morning before going to his parents and open any gifts from my family that had been sent.)
As far as your dislike of the gift they are giving you, there's really nothing you can do. LordL can suggest some ideas to his parents, or as others suggested, have him modify his gift list to joint type gifts.
