How to Enjoy Manga and Anime

I don't read the original novels, but I enjoy manga (tankobon) and then wait for anime adaptations of interesting works. For older series like Dragon Ball and Slam Dunk, or even One Piece which is still ongoing, anime adaptations of works without original novels can never surpass the manga. For Dragon Ball, battle scenes that were about 5 pages in the manga would often last for about 2 hours (lol). However, with recent anime adaptations originating from original novels and then becoming comics, there are more and more works where the anime easily gets ahead of the tankobon (though it seems they don't surpass magazine serialization). My current favorite manga is 'That Time I Got Reincarnated as a Slime,' and the anime has already progressed past volume 33... So, I haven't even taken volume 33 out of its plastic wrap yet (lol).
