Seems pretty detailed, which I guess for a guy of my generation who is accustomed to low-brow slapstick humor in my animation experiences...I struggle getting interested in anything deeper than that..
I understand completely.
Out of curiosity - Did you ever see Heavy Metal? Did you like it? Or did you have the same problem?
I understand tat cartoons are just not a form of story-telling Americans are conditioned to seeing as "serious". Cartoons are for Bugs Bunny , Scooby-doo and the Flintstones and only children watch them. If you can't get over that hurdle in your mind then Anime will never work for you.. But given the cesspool of American made crap, it may be worth a little effort to try.
Unlike American made TV, when the Japanese set out to produce a show, they already know the beginning, middle and end of the story arc, and while some series introduce filler episodes that do nothing to advance the plot ( if you see an episode count over 100, that is what is happening) most productions have 12, or 26 episodes in which to tell their story, there probably won't be a followup series, and if there is, it will be a different story arc. Most anime are adapted from already established and well liked Manga, so the stories have been through a sort of quality control, and unlike Hollywood, Anime directors understand deviating from the Manga is usually a bad thing to do.
There is a live cinematography version of Space Battleship Yamato ( actually its what started me on my adult Yamato kick) - you can rent it for $5 on Amazon and for what it is, its pretty good, but the story seriously suffers being edited from 13 hours down to 2. However, I am not sure I could have gotten my kids to watch the Anime if they hadn't seen the live action first. Maybe Yamato is the anime gateway drug, and you just need that film experience to get you hooked and wanting more? Leading you to Yamato 2199, and then to Steins;gate and Fullmetal Alchemist:Brotherhood. (IMO if you see those three, you have seen the very best the genre has to offer. There are other entertaining rides, but those stand out as exceptional.
