And that persuades people to like anime how exactly? I love the fact that every anime person you talk to says this sentence. "I was like you once." Seriously.
Guess what? I watched 1 episode of Full Metal Alchemist and I couldn't make it through, couldn't take the shit seriously and found their voices annoying. Also, I felt really uncomfortable watching it because it didn't feel right being at my age and watching cartoons.
I did the same with Attack on Titan, watched an episode with a friend who is a fan, could not take it seriously and he yelled at me for laughing at a serious scene.
Cartoons? Ha. Well anyways, the voice actors for FMA weren't anything great so that's probably why. I'll recommend Fate/Zero to you, it's got a good cast of voice actors and it'd probably suit you more. It starts getting good at episode 2, when all the action starts.
Well, i love it too.
