Anime is still, in most occasions, a cheaply made animated cartoon that is done as fast as possible with plot points being women's breast's and the hero screaming until his hair goes blonde. Plagued with filler material and bad animation, anime is a terrible source of entertainment.
The same could be said about any visual media. The truth is that there are some good movies, some good shows, and some good anime, but most are very cheaply made garbage. The lowest common denominator among all three is going to be sexuality and forced emotional conflict. It's not unique to anime.
