I've seen some anime like Initial D, Wangan Midnight, Capeta which I enjoyed very much, but that was because these anime were very focused on motorsport or cars (which I really like); I've even seen Berserk (it was alright) due to having a medieval setting. But the popular animes on the Internet and nowadays are totally different from what I saw. Stuff like Death Note, Highschool of Dead, Naruto, etc. Now I'm not going to judge them, simply because I've never saw any episode, but for example I tried to watch "School Days" that was recommended by my cousin (who is a big anime fan), but what I saw was lame teen romance and big boobs all over. I immediately erased all the episodes from my HDD after the first episode. I wanted to know if this is the main theme in anime and what is its the appeal, since anime is very popular and appreciated all over the world.
Note: I don't hate anime or make fun of people who enjoy it, I just don't grasp what the appeal is, overall.
