No. Sorry but mainstream is usually mainstream for a reason. If you like to watch 1-2 episode shows, that's good for you but I can say without confidence that the majority of people are more attracted to 20+ episodes to develop a story. Please don't start yet another Manga vs Anime debate because that's a completely personal choice. Lastly, many people who are looking for Anime haven't seen the mainstream Anime. I for one didn't see them or even know of their existence if not for the suggestions given.
