Who cares if the show is commercialize? As long as it is entertaining, what's the big deal? It's not like someone point a gun at your head forcing you to buy all the toys or posters. Some shows are so artsy that nobody watch and don't sell. To me I don't think they are better because it does not entertain me.
Call me shallow, but I don't think something that can only be appreciated by a few is necessary better.
