Agreed, the novelty of anime was a huge draw for me as well (especially since at the time there weren’t any anime-influenced Western cartoons). There are of course still standouts in anime that were revolutionary at the time and have since aged well (such as NGE and Cowboy Bebop, both of which are now over two decades old). There are also a few series that maybe weren’t masterpieces but still feel unique, as well as a handful that are cultural behemoths in and of themselves (like Gundam). But as with all media, the more you consume the more patterns emerge until the whole medium starts to feel tired.
