Anime is a medium, not a genre friend. If I were to say "film is mainstream, also highly overrated", it wouldn't make sense because there's a lot of films that cover a wide array of genres and subject matter. Anime is the same, sure there's a lot of trash, but also there's some really good stuff out there too.
Also, anime is not really "mainstream", perhaps a lot of teenagers like deathnote or something, but most people still don't really care about anime in general.
