Pork is not the most flavorful meat by a long shot. I've almost given up unless I put it in a sauce or something. It needs lots of marinade or rub to get any flavor out of it, no matter where you buy it.
I disagree. If you can find freshly butchered pork you will find that pork is wonderful with a rich, deep rich flavor. I find that most supermarket pork is insipid with little to no flavor. A friend of mine brought a pork loin roast from a local farm and it was amazing!
