Cook it like you would deer or beef. It shouldn't have too much of a wild taste. You said it was a "giant" moose. Was it really old? That could be part of the problem.
I've always found moose to be one of the best tasting wild meats. Mild and tender. Try barbecueing steaks with a little Mrs. dash or you favorite bbq sauce. Roasts are great in a slow cooker. I love coming home from work, walking in the door and smelling that delicious roast.
Try any marinade if you want a different flavour.
