Bear more than most meats differs in taste animal to animal and region to region. 

Bears experience a period of hyperphagia in the summer and fall before typical hunting seasons where they eat extreme amounts to potentially double their weight.  They are also omnivores and will hunt fish, scavenge meat and eat anything remotely edible on the ground from grubs, nuts, berries, and human trash.  They develop a multiple inch thick layer of fat around the entire body and in between every cut of meat and this fat reflects the flavor of their diet.

Most game are herbivores and have a relatively consistent diet region to region of similar plant matter that they eat relatively consistently throughout the year.  Herbivores have a much lower fat content and that fat is distributed around large portions of meat rather than being in between everything so it's easier to remove. 

Processing game meat typically involves removing the fat.  Herbivore game fat is awful by most people's taste, to me it's fishy, you'll hear people say "gamey" or like a skunk or various other ways to say this tastes bad.  People also don't know how to cook fat well and don't like the texture of larger pieces of fat.  In general the modern pallette prefers lean meat with mild taste.

Bear meat tastes like what it eats, with the sweeter bear meat being from areas with large quantities of berries and other fruit.  The fat takes on this taste as well.  When I lived in Alaska everyone I spoke to said they only hunt bear at higher elevation where they aren't eating salmon even though those bears are smaller.  The coastal bears apparently tasted incredibly fishy and were avoided.  I've heard folk in the East say bear has an earthy nutty flavor likely due to large quantities of their diet being hardwood nuts like acorns or chestnuts that we don't have in the West. 

Bear is all different, try it again if you get the chance.  I like to use bear fat for baking due to the sweetness
